Go Redis-like Key-Value Store

This project is a simple Redis-like in-memory key-value store implemented in Go. It supports basic operations such as GET, PUT, and DELETE, and uses sharding for concurrency. The server exposes a RESTful API and logs all events and errors to a file.

Features

• In-memory key-value storage
• Sharding for concurrent access
• RESTful API using Gorilla Mux
• File-based event and error logging
• Simple custom hash function for sharding

API Endpoints

PUT (Create a new key)

• URL: /v1/{key}
• Method: PUT
• Body: Raw value (string)
• Response: key added successfully{key:<key>}
• Error: 409 Conflict if key already exists

GET (Retrieve a value)

• URL: /v1/{key}
• Method: GET
• Response: Value as plain text
• Error: 409 Conflict if key does not exist

DELETE (Delete a key)

• URL: /v1/delete/{key}
• Method: GET
• Response: sucessfully deleted key :<key>
• Error: 409 Conflict if key does not exist

Logging

• All events and errors are logged to tmp.log in the project directory.

Running the Server

1. Install dependencies:

   go mod tidy

2. Run the server:

   go run cmd/main.go

3. The server will start on http://localhost:8080

Example Usage

• Add a key:

  curl -X PUT http://localhost:8080/v1/mykey -d 'myvalue'

• Get a key:

  curl http://localhost:8080/v1/mykey

• Delete a key:

  curl http://localhost:8080/v1/delete/mykey

Project Structure

• cmd/main.go: Main application code
• go.mod, go.sum: Go module files
• tmp.log: Log file (created at runtime)
