go-mock-redis

go-mock-redis is a simplified, single-threaded implementation of Redis in Go. It is designed to serve as a learning tool and a mock Redis server for testing purposes.

Requirements

  • Go 1.20 or higher

Features

  • Single-threaded: The entire server runs in a single goroutine, emulating Redis's single-threaded nature. This ensures that commands are processed sequentially, providing a simple and predictable execution model.
  • Pipelines and Multiplexers: go-mock-redis supports pipelining, allowing clients to send multiple commands to the server without waiting for each response. This can significantly improve performance by reducing network latency.
  • Data Structures: go-mock-redis implements various Redis data structures, including strings, queues, sets, and sorted sets (zsets).
  • REPL: go-mock-redis includes a REPL (read-eval-print loop) that allows users to interact with the server via a command line interface.
  • ZeroCopy: go-mock-redis uses zero-copy techniques sendfile to avoid unnecessary memory allocations and copies. This improves performance and reduces memory usage.
  • RESP: go-mock-redis uses the RESP3 (REdis Serialization Protocol) to communicate with clients. This allows it to be compatible with existing Redis clients.
