Enable the valkey (or redis compatible) integration. When enabled, the internal cache is stored in valkey instead of in memory, so it is shared between all instances and survives restarts. Required for DATABASE_REQUEST_OPTIMIZATION 'hard'. When using 'hard' mode, it is strongly recommended to enable persistence (AOF) on the valkey server, as buffered notes that have not been flushed yet only exist in valkey.
In 'hard' request optimization mode, buffered writes are flushed to the database after this many seconds at the latest.
In 'hard' request optimization mode, buffered writes are flushed to the database as soon as this many entries are pending, even if the flush interval has not elapsed yet.
