Vihang Karajgaonkar commented on IMPALA-7973:
---------------------------------------------
Yes, this would introduce a new configuration and it would need documentation
support so that users are aware of what to expect and how to use this feature.
> Add support for fine-grained updates at partition level

> 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.
