#### Default cluster snapshot implementation (existing) - Takes snapshot of the tables in the configured list `[{imem,imem_snap,snapshotClusterTables}]` - Puts these snapshots a folder and zips the folder - executes everyday at `[{imem,imem_snap,snapshotClusterHourOfDay}]` - can be enabled or disabled with `[{imem,imem_snap,snapshotCluster}]` #### New feature : support for custom cluster snapshot - list of sqls (instead of table names). gives more control over data - filter fun associated with each sql to filter the data after the execution of sql to remove certain rows or modify them - configuration flag to enable and disable the custom snapshot - configuration for cluster snapshot zip file name
