ATM: A Lightweight In-Memory Database

ATM is a lightweight, high-performance in-memory database written in Go, designed to provide key-value storage similar to Redis. It supports efficient storage and retrieval of data, enabling developers to build fast and scalable applications.

---

Features

• Key-Value Storage: Store and retrieve data with ease using a simple key-value mechanism.
• High Performance: Built for speed with an emphasis on low-latency data operations.
• Concurrency: Leverages Go’s concurrency model for handling multiple requests simultaneously.
• Persistence (Optional): Support for saving in-memory data to disk for durability.
• Minimal Dependencies: Built using Go's standard library for simplicity and reliability.
• Extensible Protocol: Easily add new features or integrate with existing systems.

Getting Started

Installation

1. Clone the repository:

   git clone https://github.com/teamcutter/atm.git
   cd atm

2. Build the application:

   go build

3. Run the server:

   ./atm -pass 12345 -login user -p :8001 

Usage

1. Start the server:
   Run the ATM server as described above.

2. Interact with the database:
   Use any TCP client (e.g., netcat or custom tools) to interact with the server. Example commands:

   • Set a key-value pair:

     SET mykey myvalue

   • Retrieve a value by key:

     GET mykey

   • Delete a key:

     DEL mykey

   You can also use client:

   • Simply run:

     go run cmd/client/main.go

   • Make http request:

     localhost:8080/set/key/value
     localhost:8080/get/key
     localhost:8080/del/key
     

3. Custom Protocol:
   The server communicates using a lightweight, custom protocol for simplicity and efficiency.
