ember-server

the main server binary for ember. accepts TCP connections, parses RESP3 commands, routes them through the sharded engine, and writes responses back. supports pipelining.

what's in here

• main — CLI arg parsing (host, port, max-memory, eviction policy, persistence config)
• server — TCP accept loop with configurable connection limits, spawns a handler task per client
• connection — per-connection event loop: read → parse frames → dispatch commands → write responses. handles idle timeouts, buffer limits, and protocol errors
• config — configuration helpers for byte sizes, eviction policies, fsync policies
