> Initially, Spark SQL does not store any partition information in the catalog for data source tables, because initially it was designed to work with arbitrary files. This, however, has a few issues for catalog tables:
> 1. Listing partitions for a large table (with millions of partitions) can be very slow during cold start.
> 2. Does not support heterogeneous partition naming schemes.
> 3. Cannot leverage pushing partition pruning into the metastore.
> This ticket tracks the work required to push the tracking of partitions into the metastore. This change should be feature flagged.
