Yu-Wen Lai has uploaded a new patch set (#5). ( http://gerrit.cloudera.org:8080/17538 )
Change subject: IMPALA-10724: Add mutable validWriteIdList ...................................................................... IMPALA-10724: Add mutable validWriteIdList In this patch, we add a new class for manually updating writeIdList. In terms of updating writeIdList, we introduce three methods including addOpenWriteId, addAbortedWriteIds, and addCommittedWriteIds. We will use this class in MetastoreEventProcessor for fine-grained table refreshing. With the control of writeIdList, we will be able to update the transactional table partially and keep it consistent. There are some restrictions for MutableValidWriteIdList. 1. We need to mark a writeId open before mark it committed/aborted. 2. We only allow two writeId state transitions, open -> committed or open -> aborted. Any other transition is NOT allowed.
