    Description

      When data is inserted into a partition or a new partition is created in a large table, we should not be invalidating the whole table. Instead it should be possible to refresh/add/drop certain partitions on the table directly based on the event information. This would help with the performance of subsequent access to the table by avoiding reloading the large table.
