Add feature view versioning support to MySQL online store #6169
Description
Summary
Add versioned feature view read/write support to the MySQL online store, so that version-qualified feature references (e.g., driver_stats@v2:trips_today) resolve to the correct versioned data.
Context
Feature view versioning was introduced in #6101. Currently, only the SQLite online store supports versioned reads/writes. All other online stores raise VersionedOnlineReadNotSupported when a versioned ref is used.
The implementation pattern (see sqlite.py for reference) involves:
- Write path: When
enable_online_feature_view_versioning is enabled, materialize data into a version-specific table/key namespace (e.g., {project}_{fv_name}_v{version})
- Read path: Route version-qualified lookups to the correct versioned table/key namespace
Reference implementation
- SQLite online store:
sdk/python/feast/infra/online_stores/sqlite.py
- Store file:
sdk/python/feast/infra/online_stores/mysql_online_store/mysql.py
