Allow Caching of Read Files for Object Storage Tables and Data Lakes

Why it matters

This feature improves cache efficiency and accuracy for object storage data sources by uniquely identifying files using their ETag and path. It ensures that cached data corresponds exactly to the current file version, reducing unnecessary data reads and improving query performance.

How to use it

The caching mechanism automatically uses the hash of the ETag and file path as the cache key when reading files from object storage table engines and data lakes. No special user actions are required beyond enabling caching features for these table types.
