Guanghao Zhang created HBASE-23286: -------------------------------------- Summary: 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 Reporter: Guanghao Zhang
After HBASE-20724, the compaction event marker is not used anymore when failover. So our new proposal is split WAL to HFile to imporve MTTR. It has 3 steps: # Read WAL and write HFile to region’s column family’s recovered.hfiles directory. # Open region. # Bulkload the recovered.hfiles for every column family. The design doc was attathed by a google doc. Any suggestions are welcomed. -- This message was sent by Atlassian Jira (v8.3.4#803005)
