chenxu commented on HBASE-23286:
--------------------------------
Can we write HFile to target CF dir directly instead of recovered.hfiles, when
opening region no need to do bulkload any more.
If doing bulkload we should bypass the BulkLoadMarker write? or bulkload
replication will have a side effect.
> Improve MTTR: Split WAL to HFile

> Project: HBase
> Issue Type: Improvement
> Components: MTTR
> Reporter: Guanghao Zhang
> Assignee: Guanghao Zhang
> Priority: Major
>
> 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.
