SELECT

Protocols: Redis RESP2

Selects a logical database by index. fastcached has a single flat keyspace, so SELECT is accepted as a no-op for compatibility: any index replies +OK and the index is ignored.

Synopsis

SELECT <index>

Response

  • Always +OK\r\n, regardless of the index.

The command exists only so a Redis client library whose connection URL names a database (for example redis://host/0) completes its setup instead of erroring. There is no per-database isolation — all keys share one space.
