> Fine grained table refreshing at partition level events for transactional

> Key: IMPALA-10923
> URL: https://issues.apache.org/jira/browse/IMPALA-10923
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Reporter: Yu-Wen Lai
> Assignee: Yu-Wen Lai
> Priority: Major
> Fix For: Impala 4.1.0
>
>
> For ensuring the transactional tables are consistent, we currently take whole
> table refreshing even a change is just for a partition only. That is too
> expensive and possibly make event processing has a longer delay.
> To enable fine-grained table refreshing, there are three main changes in this
> proposal.
> # maintain validWriteIdList in Catalogd for transactional tables. We will
> track write id changes by AllocWriteIdEvents, CommitTxnEvents, and
> AbortTxnEvents.
> # trigger partition level refreshing for addPartitionEvents,
> dropPartitionEvents, and AlterPartitionEvents.
> # Introduce a config *incremental_refresh_acid*, which can switch on/off the
> fine-grained table refreshing
