Valkey is the Linux Foundation community fork of Redis and a first-class managed engine on major clouds, but the docs could not answer whether Feast supports it. Add a page following the Dragonfly precedent: Feast's Redis online store issues only core commands, so Valkey works via type: redis with no code change. Verified against Valkey 8.1: feast apply, materialize, online retrieval, teardown, and key_ttl_seconds expiry all behave identically to Redis. Module-dependent features (e.g. vector search) are explicitly out of scope on the page. Signed-off-by: Larry Singleton <166439969+larrysingleton007@users.noreply.github.com>
The bigtable block in the online stores index pointed its link text at mysql.md, a copy-paste slip. Point it at bigtable.md. Signed-off-by: Larry Singleton <166439969+larrysingleton007@users.noreply.github.com>

What this PR does / why we need it
Adds a documentation page for using Valkey as the online store. Valkey is the Linux Foundation community fork of Redis and a first-class managed engine on major clouds (e.g. Amazon ElastiCache), but the docs currently can't answer whether Feast supports it, and there's no
valkeymention anywhere in the repo.The docs already sanction exactly this pattern for Dragonfly: a docs-only page saying install
feast[redis], settype: redis, point it at the compatible store. This page follows that precedent, placed next todragonfly.mdin the index andSUMMARY.md.Unlike a pure protocol argument, the compatibility claim here is verified: against Valkey 8.1,
feast apply,feast materialize, online retrieval viaget_online_features,feast teardown, andkey_ttl_secondsexpiry all behave identically to Redis. That holds because the Redis online store only issues core commands (hash reads/writes, scans, expiry, pipelines). The page states what was verified and explicitly scopes out module-dependent features like vector search. No code changes, and no row added to the overview functionality matrix (Dragonfly doesn't have one either).A second commit fixes an adjacent copy-paste slip in the online stores index: the bigtable content-ref linked its text to
mysql.md.Which issue(s) this PR fixes
None (docs-only, following the Dragonfly precedent).
