I understand the Delta caching for the data files. Do we have anything similar for the metadata files. Will the delta metadata get cached in the Delta caching

The Delta logs - JSON files will be cached on the Driver (in memory) for Delta if they are small enough (<10 MB). They are not stored in the Delta cache.

Before every query Delta checks if the snapshot is stale or has to be re-built.
