A given running memcached server listens on some +(configurable) port; clients connect to that port, send commands to +the server, read responses, and eventually close the connection. + +There is no need to send any command to end the session. A client may +just close the connection at any moment it no longer needs it. Note, +however, that clients are encouraged to cache their connections rather +than reopen them every time they need to store or retrieve data. This +is because memcached is especially designed to work very efficiently +with a very large number (many hundreds, more than a thousand if +necessary) of open connections. Caching connections will eliminate the +overhead associated with establishing a TCP connection (the overhead +of preparing for a new connection on the server side is insignificant +compared to this). + +There are two kinds of data sent in the memcache protocol: text lines +and unstructured data. Text lines are used for commands from clients +and responses from servers. Unstructured data is sent when a client +wants to store or retrieve data. The server will transmit back +unstructured data in exactly the same way it received it, as a byte +stream. The server doesn't care about byte order issues in +unstructured data and isn't aware of them. There are no limitations on +characters that may appear in unstructured data; however, the reader +of such data (either a client or a server) will always know, from a +preceding text line, the exact length of the data block being +transmitted. + +Text lines are always terminated by \r\n. Unstructured data is _also_ +terminated by \r\n, even though \r, \n or any other 8-bit characters +may also appear inside the data. Therefore, when a client retrieves +data from a server, it must use the length of the data block (which it +will be provided with) to determine where the data block ends, and not +the fact that \r\n follows the end of the data block, even though it +does. + +Keys +---- + +Data stored by memcached is identified with the help of a key. A key +is a text string which should uniquely identify the data for clients +that are interested in storing and retrieving it. Currently the +length limit of a key is set at 250 characters (of course, normally +clients wouldn't need to use such long keys); the key must not include +control characters or whitespace. + +Commands +-------- + +There are three types of commands. + +Storage commands (there are six: "set", "add", "replace", "append" +"prepend" and "cas") ask the server to store some data identified by a +key. The client sends a command line, and then a data block; after +that the client expects one line of response, which will indicate +success or failure. + +Retrieval commands ("get", "gets", "gat", and "gats") ask the server to +retrieve data corresponding to a set of keys (one or more keys in one +request). The client sends a command line, which includes all the +requested keys; after that for each item the server finds it sends to +the client one response line with information about the item, and one +data block with the item's data; this continues until the server +finished with the "END" response line. + +All other commands don't involve unstructured data. In all of them, +the client sends one command line, and expects (depending on the +command) either one line of response, or several lines of response +ending with "END" on the last line. + +A command line always starts with the name of the command, followed by +parameters (if any) delimited by whitespace. Command names are +lower-case and are case-sensitive. + +Meta Commands +------------- + +Meta commands are a set of new ASCII-based commands. They follow the same +structure of the original commands but have a new flexible feature set. +Meta commands incorporate most features available in the binary protocol, as +well as a flag system to make the commands flexible rather than having a +large number of high level commands. These commands completely replace the +usage of basic Storage and Retrieval commands. + +Meta flags are not to be confused with client bitflags, which is an opaque +number passed by the client. Meta flags change how the command operates, but +they are not stored in cache. + +These work mixed with normal protocol commands on the same connection. All +existing commands continue to work. The meta commands will not replace +specialized commands that do not sit in the Storage or Retrieval categories +noted in the 'Commands' section above. + +All meta commands follow a basic syntax: + + <...>\r\n + +Where is a 2 character command code. + is only for commands with payloads, like set. + +Responses look like: + + <...>\r\n + +Where is a 2 character return code. The number of flags returned are +based off of the flags supplied. + + is only for responses with payloads, with the return code 'VA'. + +Flags are single character codes, ie 'q' or 'k' or 'I', which adjust the +behavior of the command. If a flag requests a response flag (ie 't' for TTL +remaining), it is returned in the same order as they were in the original +command, though this is not strict. + +Flags are single character codes, ie 'q' or 'k' or 'O', which adjust the +behavior of a command. Flags may contain token arguments, which come after the +flag and before the next space or newline, ie 'Oopaque' or 'Kuserkey'. Flags +can return new data or reflect information, in the same order they were +supplied in the request. Sending an 't' flag with a get for an item with 20 +seconds of TTL remaining, would return 't20' in the response. + +All commands accept a tokens 'P' and 'L' which are completely ignored. The +arguments to 'P' and 'L' can be used as hints or path specifications to a +proxy or router inbetween a client and a memcached daemon. For example, a +client may prepend a "path" in the key itself: "mg /path/foo v" or in a proxy +token: "mg foo Lpath/ v" - the proxy may then optionally remove or forward the +token to a memcached daemon, which will ignore them. + +Syntax errors are handled the same as noted under 'Error strings' section +below. + +For usage examples beyond basic syntax, please see the wiki: +https://github.com/memcached/memcached/wiki/MetaCommands + +Expiration times +---------------- + +Some commands involve a client sending some kind of expiration time +(relative to an item or to an operation requested by the client) to +the server. In all such cases, the actual value sent may either be +Unix time (number of seconds since January 1, 1970, as a 32-bit +value), or a number of seconds starting from current time. In the +latter case, this number of seconds may not exceed 60*60*24*30 (number +of seconds in 30 days); if the number sent by a client is larger than +that, the server will consider it to be real Unix time value rather +than an offset from current time. + +Note that a TTL of 1 will sometimes immediately expire. Time is internally +updated on second boundaries, which makes expiration time roughly +/- 1s. +This more proportionally affects very low TTL's. + +Error strings +------------- + +Each command sent by a client may be answered with an error string +from the server. These error strings come in three types: + +- "ERROR\r\n" + + means the client sent a nonexistent command name. + +- "CLIENT_ERROR \r\n" + + means some sort of client error in the input line, i.e. the input + doesn't conform to the protocol in some way. is a + human-readable error string. + +- "SERVER_ERROR \r\n" + + means some sort of server error prevents the server from carrying + out the command. is a human-readable error string. In cases + of severe server errors, which make it impossible to continue + serving the client (this shouldn't normally happen), the server will + close the connection after sending the error line. This is the only + case in which the server closes a connection to a client. + + +In the descriptions of individual commands below, these error lines +are not again specifically mentioned, but clients must allow for their +possibility. + +Authentication +-------------- + +Optional username/password token authentication (see -Y option). Used by +sending a fake "set" command with any key: + +set \r\n +username password\r\n + +key, flags, and exptime are ignored for authentication. Bytes is the length +of the username/password payload. + +- "STORED\r\n" indicates success. After this point any command should work + normally. + +- "CLIENT_ERROR [message]\r\n" will be returned if authentication fails for + any reason. + +Storage commands +---------------- + +First, the client sends a command line which looks like this: + + [noreply]\r\n +cas [noreply]\r\n + +- is "set", "add", "replace", "append" or "prepend" + + "set" means "store this data". + + "add" means "store this data, but only if the server *doesn't* already + hold data for this key". + + "replace" means "store this data, but only if the server *does* + already hold data for this key". + + "append" means "add this data to an existing key after existing data". + + "prepend" means "add this data to an existing key before existing data". + + The append and prepend commands do not accept flags or exptime. + They update existing data portions, and ignore new flag and exptime + settings. + + "cas" is a check and set operation which means "store this data but + only if no one else has updated since I last fetched it." + +- is the key under which the client asks to store the data + +- is an arbitrary 16-bit unsigned integer (written out in + decimal) that the server stores along with the data and sends back + when the item is retrieved. Clients may use this as a bit field to + store data-specific information; this field is opaque to the server. + Note that in memcached 1.2.1 and higher, flags may be 32-bits, instead + of 16, but you might want to restrict yourself to 16 bits for + compatibility with older versions. + +- is expiration time. If it's 0, the item never expires + (although it may be deleted from the cache to make place for other + items). If it's non-zero (either Unix time or offset in seconds from + current time), it is guaranteed that clients will not be able to + retrieve this item after the expiration time arrives (measured by + server time). If a negative value is given the item is immediately + expired. + +- is the number of bytes in the data block to follow, *not* + including the delimiting \r\n. may be zero (in which case + it's followed by an empty data block). + +- is a unique 64-bit value of an existing entry. + Clients should use the value returned from the "gets" command + when issuing "cas" updates. + +- "noreply" optional parameter instructs the server to not send the + reply. NOTE: if the request line is malformed, the server can't + parse "noreply" option reliably. In this case it may send the error + to the client, and not reading it on the client side will break + things. Client should construct only valid requests. + +After this line, the client sends the data block: + +\r\n + +- is a chunk of arbitrary 8-bit data of length + from the previous line. + +After sending the command line and the data block the client awaits +the reply, which may be: + +- "STORED\r\n", to indicate success. + +- "NOT_STORED\r\n" to indicate the data was not stored, but not +because of an error. This normally means that the +condition for an "add" or a "replace" command wasn't met. + +- "EXISTS\r\n" to indicate that the item you are trying to store with +a "cas" command has been modified since you last fetched it. + +- "NOT_FOUND\r\n" to indicate that the item you are trying to store +with a "cas" command did not exist. + + +Retrieval command: +------------------ + +The retrieval commands "get" and "gets" operate like this: + +get *\r\n +gets *\r\n + +- * means one or more key strings separated by whitespace. + +After this command, the client expects zero or more items, each of +which is received as a text line followed by a data block. After all +the items have been transmitted, the server sends the string + +"END\r\n" + +to indicate the end of response. + +Each item sent by the server looks like this: + +VALUE []\r\n +\r\n + +- is the key for the item being sent + +- is the flags value set by the storage command + +- is the length of the data block to follow, *not* including + its delimiting \r\n + +- is a unique 64-bit integer that uniquely identifies + this specific item. + +- is the data for this item. + +If some of the keys appearing in a retrieval request are not sent back +by the server in the item list this means that the server does not +hold items with such keys (because they were never stored, or stored +but deleted to make space for more items, or expired, or explicitly +deleted by a client). + + +Deletion +-------- + +The command "delete" allows for explicit deletion of items: + +delete [noreply]\r\n + +- is the key of the item the client wishes the server to delete + +- "noreply" optional parameter instructs the server to not send the + reply. See the note in Storage commands regarding malformed + requests. + +The response line to this command can be one of: + +- "DELETED\r\n" to indicate success + +- "NOT_FOUND\r\n" to indicate that the item with this key was not + found. + +See the "flush_all" command below for immediate invalidation +of all existing items. + + +Increment/Decrement +------------------- + +Commands "incr" and "decr" are used to change data for some item +in-place, incrementing or decrementing it. The data for the item is +treated as decimal representation of a 64-bit unsigned integer. If +the current data value does not conform to such a representation, the +incr/decr commands return an error (memcached <= 1.2.6 treated the +bogus value as if it were 0, leading to confusion). Also, the item +must already exist for incr/decr to work; these commands won't pretend +that a non-existent key exists with value 0; instead, they will fail. + +The client sends the command line: + +incr [noreply]\r\n + +or + +decr [noreply]\r\n + +- is the key of the item the client wishes to change + +- is the amount by which the client wants to increase/decrease +the item. It is a decimal representation of a 64-bit unsigned integer. + +- "noreply" optional parameter instructs the server to not send the + reply. See the note in Storage commands regarding malformed + requests. + +The response will be one of: + +- "NOT_FOUND\r\n" to indicate the item with this value was not found + +- \r\n , where is the new value of the item's data, + after the increment/decrement operation was carried out. + +Note that underflow in the "decr" command is caught: if a client tries +to decrease the value below 0, the new value will be 0. Overflow in +the "incr" command will wrap around the 64 bit mark. + +Note also that decrementing a number such that it loses length isn't +guaranteed to decrement its returned length. The number MAY be +space-padded at the end, but this is purely an implementation +optimization, so you also shouldn't rely on that. + +Touch +----- + +The "touch" command is used to update the expiration time of an existing item +without fetching it. + +touch [noreply]\r\n + +- is the key of the item the client wishes the server to touch + +- is expiration time. Works the same as with the update commands + (set/add/etc). This replaces the existing expiration time. If an existing + item were to expire in 10 seconds, but then was touched with an + expiration time of "20", the item would then expire in 20 seconds. + +- "noreply" optional parameter instructs the server to not send the + reply. See the note in Storage commands regarding malformed + requests. + +The response line to this command can be one of: + +- "TOUCHED\r\n" to indicate success + +- "NOT_FOUND\r\n" to indicate that the item with this key was not + found. + +Get And Touch +------------- + +The "gat" and "gats" commands are used to fetch items and update the +expiration time of an existing items. + +gat *\r\n +gats *\r\n + +- is expiration time. + +- * means one or more key strings separated by whitespace. + +After this command, the client expects zero or more items, each of +which is received as a text line followed by a data block. After all +the items have been transmitted, the server sends the string + +"END\r\n" + +to indicate the end of response. + +Each item sent by the server looks like this: + +VALUE []\r\n +\r\n + +- is the key for the item being sent + +- is the flags value set by the storage command + +- is the length of the data block to follow, *not* including + its delimiting \r\n + +- is a unique 64-bit integer that uniquely identifies + this specific item. + +- is the data for this item. + +Meta Debug +---------- + +The meta debug command is a human readable dump of all available internal +metadata of an item, minus the value. + +me \r\n + +- means one key string. +- if is 'b', then is a base64 encoded binary value. the response + key will also be base64 encoded. + +The response looks like: + +ME =*\r\n + +A miss looks like: + +EN\r\n + +Each of the keys and values are the internal data for the item. + +exp = expiration time +la = time in seconds since last access +cas = CAS ID +fetch = whether an item has been fetched before +cls = slab class id +size = total size in bytes + +Others may be added. + +Meta Get +-------- + +The meta get command is the generic command for retrieving key data from +memcached. Based on the flags supplied, it can replace all of the commands: +"get", "gets", "gat", "gats", "touch", as well as adding new options. + +mg *\r\n + +- means one key string. Unlike "get" metaget can only take a single key. + +- are a set of single character codes ended with a space or newline. + flags may have token strings after the initial character. + +After this command, the client expects an item to be returned, received as a +text line followed by an optional data block. + +If a response line appearing in a retrieval request is not sent back +by the server this means that the server does not +have the item (because it was never stored, or stored +but deleted to make space for more items, or expired, or explicitly +deleted by a client). + +An item sent by the server looks like: + +VA *\r\n +\r\n + +- is the size of in bytes, minus the \r\n + +- * are flags returned by the server, based on the command flags. + They are added in order specified by the flags sent. + +- is the data for this item. Note that the data block is + optional, requiring the 'v' flag to be supplied. + +If the request did not ask for a value in the response (v) flag, the server +response looks like: + +HD *\r\n + +If the request resulted in a miss, the response looks like: + +EN\r\n + +Unless the (q) flag was supplied, which suppresses the status code for a miss. + +The flags used by the 'mg' command are: + +- b: interpret key as base64 encoded binary value +- c: return item cas token +- f: return client flags token +- h: return whether item has been hit before as a 0 or 1 +- k: return key as a token +- l: return time since item was last accessed in seconds +- O(token): opaque value, consumes a token and copies back with response +- q: use noreply semantics for return codes. +- s: return item size token +- t: return item TTL remaining in seconds (-1 for unlimited) +- u: don't bump the item in the LRU +- v: return item value in + +These flags can modify the item: +- E(token): use token as new CAS value if item is modified +- N(token): vivify on miss, takes TTL as a argument +- R(token): if remaining TTL is less than token, win for recache +- T(token): update remaining TTL + +These extra flags can be added to the response: +- W: client has "won" the recache flag +- X: item is stale +- Z: item has already sent a winning flag + +The flags are now repeated with detailed information where useful: + +- b: interpret key as base64 encoded binary value + +This flag instructs memcached to run a base64 decoder on before looking +it up. This allows storing and fetching of binary packed keys, so long as they +are sent to memcached in base64 encoding. + +If 'b' flag is sent in the response, and a key is returned via 'k', this +signals to the client that the key is base64 encoded binary. + +- h: return whether item has been hit before as a 0 or 1 +- l: return time since item was last accessed in seconds + +The above two flags return the value of "hit before?" and "last access time" +before the command was processed. Otherwise this would always show a 1 for +hit or always show an access time of "0" unless combined with the "u" flag. + +- O(token): opaque value, consumes a token and copies back with response + +The O(opaque) token is used by this and other commands to allow easier +pipelining of requests while saving bytes on the wire for responses. For +example: if pipelining three get commands together, you may not know which +response belongs to which without also retrieving the key. If the key is very +long this can generate a lot of traffic, especially if the data block is very +small. Instead, you can supply an "O" flag for each mg with tokens of "1" "2" +and "3", to match up responses to the request. + +Opaque tokens may be up to 32 bytes in length, and are a string similar to +keys. + +- q: use noreply semantics for return codes. + +Noreply is a method of reducing the amount of data sent back by memcached to +the client for normal responses. In the case of metaget, if an item is not +available the "VA" line is normally not sent, and the response is terminated by +"EN\r\n". + +With noreply enabled, the "EN\r\n" marker is suppressed. This allows you to +pipeline several mg's together and read all of the responses without the +"EN\r\n" lines in the middle. + +Errors are always returned. + +- u: don't bump the item in the LRU + +It is possible to access an item without causing it to be "bumped" to the head +of the LRU. This also avoids marking an item as being hit or updating its last +access time. + +- v: return item value in + +The data block for a metaget response is optional, requiring this flag to be +passed in. The response code also changes from "HD" to "VA " + +These flags can modify the item: +- E(token): use token as new CAS value if item is modified + +Normally when an item is created it is given a CAS value from an internal +atomically incrementing counter. This allows overriding the CAS (8 byte +unsigned integer) with the specified value. This is useful for using an +external system to version cache data (row versions, clocks, etc). + +- N(token): vivify on miss, takes TTL as a argument + +Used to help with so called "dog piling" problems with recaching of popular +items. If supplied, and metaget does not find the item in cache, it will +create a stub item with the key and TTL as supplied. If such an item is +created a 'W' flag is added to the response to indicate to a client that they +have "won" the right to recache an item. + +The automatically created item has 0 bytes of data. + +Further requests will see a 'Z' flag to indicate that another client has +already received the win flag. + +Can be combined with CAS flags to gate the update further. + +- R(token): if token is less than remaining TTL win for recache + +Similar to and can be combined with 'N'. If the remaining TTL of an item is +below the supplied token, return a 'W' flag to indicate the client has "won" +the right to recache an item. This allows refreshing an item before it leads to +a miss. + +- T(token): update remaining TTL + +Similar to "touch" and "gat" commands, updates the remaining TTL of an item if +hit. + +These extra flags can be added to the response: +- W: client has "won" the recache flag + +When combined with N or R flags, a client may be informed they have "won" +ownership of a cache item. This allows a single client to be atomically +notified that it should cache or update an item. Further clients requesting +the item can use the existing data block (if valid or stale), retry, wait, or +take some other action while the item is missing. + +This is used when the act of recaching an item can cause undue load on another +system (CPU, database accesses, time, and so on). + +- X: item is stale + +Items can be marked as stale by the metadelete command. This indicates to the +client that an object needs to be updated, and that it should make a decision +o if potentially stale data is safe to use. + +This is used when you want to convince clients to recache an item, but it's +safe to use pre-existing data while the recache happens. + +- Z: item has already sent a winning flag + +When combined with the X flag, or the client N or R flags, this extra response +flag indicates to a client that a different client is responsible for +recaching this item. If there is data supplied it may use it, or the client +may decide to retry later or take some other action. + +Meta Set +-------- + +The meta set command a generic command for storing data to memcached. Based +on the flags supplied, it can replace all storage commands (see token M) as +well as adds new options. + +ms *\r\n + +- means one key string. + +- is the length of the payload data. + +- are a set of single character codes ended with a space or newline. + flags may have strings after the initial character. + +After this line, the client sends the data block: + +\r\n + +- is a chunk of arbitrary 8-bit data of length supplied by an 'S' + flag and token from the request line. If no 'S' flag is supplied the data + is assumed to be 0 length. + +After sending the command line and the data block the client awaits +the reply, which is of the format: + + *\r\n + +Where CD is one of: + +- "HD" (STORED), to indicate success. + +- "NS" (NOT_STORED), to indicate the data was not stored, but not +because of an error. + +- "EX" (EXISTS), to indicate that the item you are trying to store with +CAS semantics has been modified since you last fetched it. + +- "NF" (NOT_FOUND), to indicate that the item you are trying to store +with CAS semantics did not exist. + +The flags used by the 'ms' command are: + +- b: interpret key as base64 encoded binary value (see metaget) +- c: return CAS value if successfully stored. +- C(token): compare CAS value when storing item +- E(token): use token as new CAS value (see metaget for detail) +- F(token): set client flags to token (32 bit unsigned numeric) +- I: invalidate. set-to-invalid if supplied CAS is older than item's CAS +- k: return key as a token +- O(token): opaque value, consumes a token and copies back with response +- q: use noreply semantics for return codes +- s: return the size of the stored item on success (ie; new size on append) +- T(token): Time-To-Live for item, see "Expiration" above. +- M(token): mode switch to change behavior to add, replace, append, prepend +- N(token): if in append mode, autovivify on miss with supplied TTL + +The flags are now repeated with detailed information where useful: + +- c: returns the CAS value on successful storage. Will return 0 on error, but + clients must not depend on the return value being zero. In future versions +this may return the current CAS value for "EX" return code conditions. + +- C(token): compare CAS value when storing item + +Similar to the basic "cas" command, only store item if the supplied token +matches the current CAS value of the item. When combined with the 'I' flag, a +CAS value that is _lower_ than the current value may be accepted, but the item +will be marked as "stale", returning the X flag with mget requests. + +- F(token): set client flags to token (32 bit unsigned numeric) + +Sets flags to 0 if not supplied. + +- I: invalid. set-to-invalid if CAS is older than it should be. + +Functional when combined with 'C' flag above. + +- O(token): opaque value, consumes a token and copies back with response + +See description under 'Meta Get' + +- q: use noreply semantics for return codes + +Noreply is a method of reducing the amount of data sent back by memcached to +the client for normal responses. In the case of metaset, a response that +would start with "HD" will not be sent. Any other code, such as "EX" +(EXISTS) will still be returned. + +Errors are always returned. + +- M(token): mode switch. Takes a single character for the mode. + +E: "add" command. LRU bump and return NS if item exists. Else +add. +A: "append" command. If item exists, append the new value to its data. +P: "prepend" command. If item exists, prepend the new value to its data. +R: "replace" command. Set only if item already exists. +S: "set" command. The default mode, added for completeness. + +The "cas" command is supplanted by specifying the cas value with the 'C' flag. +Append and Prepend modes will also respect a supplied cas value. + +- N(token): if in append mode, autovivify on miss with supplied TTL + +Append and Prepend modes normally ignore the T argument, as they cannot create +a new item on a miss. If N is supplied, and append reaches a miss, it will +create a new item seeded with the data from the append command. It uses the +TTL from N instead of T to be consistent with the usage of N in other +commands. + +Meta Delete +----------- + +The meta delete command allows for explicit deletion of items, as well as +marking items as "stale" to allow serving items as stale during revalidation. + +md *\r\n + +- means one key string. + +- are a set of single character codes ended with a space or newline. + flags may have strings after the initial character. + +The response is in the format: + + *\r\n + +Where CD is one of: + +- "HD" (DELETED), to indicate success + +- "NF" (NOT_FOUND), to indicate that the item with this key was not found. + +- "EX" (EXISTS), to indicate that the supplied CAS token does not match the + stored item. + +The flags used by the 'md' command are: + +- b: interpret key as base64 encoded binary value (see metaget) +- C(token): compare CAS value +- E(token): use token as new CAS value (see metaget for detail) +- I: invalidate. mark as stale, bumps CAS. +- k: return key +- O(token): opaque to copy back. +- q: noreply +- T(token): updates TTL, only when paired with the 'I' flag +- x: removes the item value, but leaves the item. + +The flags are now repeated with detailed information where useful: + +- C(token): compare CAS value + +Can be used to only delete or mark-stale if a supplied CAS value matches. + +- I: invalidate. mark as stale, bumps CAS. + +Instead of removing an item, this will give the item a new CAS value and mark +it as stale. This means when it is later fetched by metaget, the client will +be supplied an 'X' flag to show the data is stale and needs to be recached. + +- O(token): opaque to copy back. + +See description under 'Meta Get' + +- q: noreply + +See description under 'Meta Set'. In the case of meta delete, this will hide +response lines with the code "DE". It will still return any other responses. + +- T(token): updates TTL, only when paired with the 'I' flag + +When marking an item as stale with 'I', the 'T' flag can be used to update the +TTL as well; limiting the amount of time an item will live while stale and +waiting to be recached. + +- x: removes the item value, but leaves the item. + +This deletes the value off of an item (by replacing it with an empty value +item atomically). Combined with I this can leave what is effectively a +tombstone of a previous value. + +Meta Arithmetic +--------------- + +The meta arithmetic command allows for basic operations against numerical +values. This replaces the "incr" and "decr" commands. Values are unsigned +64bit integers. Decrementing will reach 0 rather than underflow. Incrementing +can overflow. + +ma *\r\n + +- means one key string. + +- are a set of single character codes ended with a space or newline. + flags may have strings after the initial character. + +The response is in the format: + + *\r\n + +Where CD is one of: + +- "HD" to indicate success + +- "NF" (NOT_FOUND), to indicate that the item with this key was not found. + +- "NS" (NOT_STORED), to indicate that the item was not created as requested + after a miss. + +- "EX" (EXISTS), to indicate that the supplied CAS token does not match the + stored item. + +If the 'v' flag is supplied, the response is formatted as: + +VA *\r\n +\r\n + +The flags used by the 'ma' command are: + +- b: interpret key as base64 encoded binary value (see metaget) +- C(token): compare CAS value (see mset) +- E(token): use token as new CAS value (see metaget for detail) +- N(token): auto create item on miss with supplied TTL +- J(token): initial value to use if auto created after miss (default 0) +- D(token): delta to apply (decimal unsigned 64-bit number, default 1) +- T(token): update TTL on success +- M(token): mode switch to change between incr and decr modes. +- O(token): opaque value, consumes a token and copies back with response +- q: use noreply semantics for return codes (see details under mset) +- t: return current TTL +- c: return current CAS value if successful. +- v: return new value +- k: return key as a token + +The flags are now repeated with detailed information where useful: + +- C(token): compare CAS value + +Can be used to only incr/decr if a supplied CAS value matches. A new CAS value +is generated after a delta is applied. Add the 'c' flag to get the new CAS +value after success. + +- N(token): auto create item on miss with supplied TTL + +Similar to mget, on a miss automatically create the item. A value can be +seeded using the J flag. + +- J(token): initial value + +An unsigned 64-bit integer which will be seeded as the value on a miss. Must be +combined with an N flag. + +- D(token): delta to apply + +An unsigned integer to either add or subtract from the currently stored +number. + +- T(token): update TTL + +On success, sets the remaining TTL to the supplied value. + +-M(token): mode switch. Takes a single character for the mode. + +I: Increment mode (default) ++: Alias for increment +D: Decrement mode +-: Alias for decrement + +Meta No-Op +---------- + +The meta no-op command exists solely to return a static response code. It +takes no flags, no arguments. + +"mn\r\n" + +This returns the static response: + +"MN\r\n" + +This command is useful when used with the 'q' flag and pipelining commands. +For example, with 'mg' the response lines are blank on miss when the 'q' flag +is supplied. If pipelining several 'mg's together with noreply semantics, an +"mn\r\n" command can be tagged to the end of the chain, which will return an +"MN\r\n", signalling to a client that all previous commands have been +processed. + +Slabs Reassign +-------------- + +NOTE: This command is subject to change as of this writing. + +The slabs reassign command is used to redistribute memory once a running +instance has hit its limit. It might be desirable to have memory laid out +differently than was automatically assigned after the server started. + +slabs reassign \r\n + +- is an id number for the slab class to steal a page from + +A source class id of -1 means "pick from any valid class" + +- is an id number for the slab class to move a page to + +The response line could be one of: + +- "OK" to indicate the page has been scheduled to move + +- "BUSY [message]" to indicate a page is already being processed, try again + later. + +- "BADCLASS [message]" a bad class id was specified + +- "NOSPARE [message]" source class has no spare pages + +- "NOTFULL [message]" dest class must be full to move new pages to it + +- "UNSAFE [message]" source class cannot move a page right now + +- "SAME [message]" must specify different source/dest ids. + +Slabs Automove +-------------- + +NOTE: This command is subject to change as of this writing. + +The slabs automove command enables a background thread which decides on its +own when to move memory between slab classes. Its implementation and options +will likely be in flux for several versions. See the wiki/mailing list for +more details. + +The automover can be enabled or disabled at runtime with this command. + +slabs automove <0|1|2> + +- 0|1|2 is the indicator on whether to enable the slabs automover or not. + +The response should always be "OK\r\n" + +- <0> means to set the thread on standby + +- <1> means to return pages to a global pool when there are more than 2 pages + worth of free chunks in a slab class. Pages are then re-assigned back into + other classes as-needed. + +- <2> is a highly aggressive mode which causes pages to be moved every time + there is an eviction. It is not recommended to run for very long in this + mode unless your access patterns are very well understood. + +LRU Tuning +---------- + +Memcached supports multiple LRU algorithms, with a few tunables. Effort is +made to have sane defaults however you are able to tune while the daemon is +running. + +The traditional model is "flat" mode, which is a single LRU chain per slab +class. The newer (with `-o modern` or `-o lru_maintainer`) is segmented into +HOT, WARM, COLD. There is also a TEMP LRU. See doc/new_lru.txt for details. + +lru
