--------------------------------------
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.
