Michael Stack commented on HBASE-24382:
---------------------------------------
>From PR, on why this feature: "It is from a discussion ... whether a table
>could be set many column family(10~100) or not. If yes, we can store columns
>to individual column family, and will be easily to do column pruning in olap
>query. Flushing all stores of reigon caused by wal make it hard, so i think
>maybe it worth to do the change."
> Flush partial stores of region filtered by seqId when archive wal due to too
> many wals

> Components: wal
> Reporter: Zheng Wang
> Assignee: Zheng Wang
> Priority: Major

> When the logRoller archive the oldest wal due to too many wals, if a region
> should be flushed, we flush all stores of it, but it is not necessary, maybe
> we can use unflushedSeqId of store to filter them.
