Read WAL and write HFile to region’s column family’s recovered.hfiles directory. 2. Open region. 3. Bulkload the recovered.hfiles for every column family. Compared to DLS(distributed log split), this feature will reduce region open time significantly. Config hbase.wal.split.to.hfile to true to enable this featue. > Improve MTTR: Split WAL to HFile > > > Key: HBASE-23286 > URL: https://issues.apache.org/jira/browse/HBASE-23286 > Project: HBase > Issue Type: Improvement > Components: MTTR >Affects Versions: 3.0.0, 2.3.0 >Reporter: Guanghao Zhang >Assignee: Guanghao Zhang >Priority: Major > Fix For: 3.0.0, 2.3.0 > > > After HBASE-20724, the compaction event marker is not used anymore when > failover.
