The sentinel stores hardcoded a 30s read timeout and a 1m retry backoff.
After a sentinel failover every request that picked a pooled connection to
the old master sat there for 30s before the connection was retired, and the
pool timeout derived from it (read timeout + 1s) queued the rest behind
them. The other redis stores took the go-redis defaults with no way to tune
anything.
Read the dial, timeout and pool knobs from each redis store section instead,
keeping the go-redis default for every key left unset.
The scaffold advertises enable_tls, ca_cert_path, client_cert_path and
client_key_path under redis2, redis2_sentinel and redis_cluster2, but only the
plain redis2 and redis3 stores ever read them, and under a different name,
enable_mtls. Sentinel and cluster setups quietly connected in plaintext.
Build the TLS config in one place and use it from all six stores. enable_mtls
still works. The CA and the client key pair are optional now, so enable_tls
alone verifies against the system roots, and ServerName is left unset so
go-redis validates each address the sentinel and cluster clients dial.
* filer: add username and keyPrefix support for Redis stores
Addresses https://github.com/seaweedfs/seaweedfs/issues/7299
- Add username config option to redis2, redis_cluster2, redis_lua, and
redis_lua_cluster stores (sentinel stores already had it)
- Add keyPrefix config option to all Redis stores to prefix all keys,
useful for Envoy Redis Proxy or multi-tenant Redis setups
* refactor: reduce duplication in redis.NewClient creation
Address code review feedback by defining redis.Options once and
conditionally setting TLSConfig instead of duplicating the entire
NewClient call.
* filer.toml: add username and keyPrefix to redis2.tmp example
