stack resolved HBASE-12405. --------------------------- Resolution: Duplicate Dup of HBASE-10201 at [~Apache9]'s request > WAL accounting by Store > ----------------------- > > Key: HBASE-12405 > URL: https://issues.apache.org/jira/browse/HBASE-12405 > Project: HBase > Issue Type: Improvement > Components: wal > Reporter: zhangduo > Assignee: zhangduo > > HBASE-10201 has made flush decisions per Store, but has not done enough work > on HLog, so there are two problems: > 1. We record minSeqId both in HRegion and FSHLog, which is a duplication. > 2. There maybe holes in WAL accounting. > For example, assume family A with sequence id 1 and 3, family B with > seqId 2. If we flush family A, we can only record that WAL before sequence id > 1 can be removed safely. If we do a replay at this point, sequence id 3 will > also be replayed which is unnecessary. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
