Change subject: IMPALA-10923: Fine grained table refreshing at partition level events for transactional tables ...................................................................... IMPALA-10923: Fine grained table refreshing at partition level events for transactional tables To enable fine-grained table refreshing, there are three main changes in this commit. 1. Maintain validWriteIdList in Catalogd for transactional tables. We will keep track of write id changes for partitioned tables by AllocWriteIdEvents, CommitTxnEvents, and AbortTxnEvents. 2. Conduct partition level refreshing for transactional tables addPartitionEvents, dropPartitionEvents, and AlterPartitionEvents. 3. Introduce a config hms_event_incremental_refresh_transactional_table, which can switch on/off the fine-grained table refreshing. Performance Tests: A simple test was performed by running insert into one partition for partitioned ACID tables (50,000 partitions). Below are the time taken to refresh this table by the event.
