Project steps

  1. 01

    In-memory storage

    map[string][]byte protected with sync.RWMutex for Get/Set/Delete operations.

  2. 02

    Write-Ahead Log

    Before each mutation, write op+key+value to the WAL (append-only file).

  3. 03

    Recovery

    On startup, replay the WAL to reconstruct the in-memory state.

  4. 04

    TCP Protocol

    TCP server with text commands: SET key value, GET key, DEL key, KEYS *.

  5. 05

    Compaction

    Periodically, compact the WAL by writing a snapshot and truncating the old log.
