Attachment: HBASE-2375-flush-split.patch
Patch that I posted in HBASE-2375 that Stack +1'd.
> Consider splitting after flushing
> ---------------------------------
>
> Key: HBASE-5393
> URL: https://issues.apache.org/jira/browse/HBASE-5393
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.90.5
> Reporter: Jean-Daniel Cryans
> Assignee: Jean-Daniel Cryans
> Fix For: 0.94.0
>
> Attachments: HBASE-2375-flush-split.patch

> Spawning this from HBASE-2375, I saw that it was much more efficient
> compaction-wise to check if we can split right after flushing. Much like the
> ideas that Jon spelled out in the description of that jira, the window is
> smaller because you don't have to compact and then split right away to only
> compact again when the daughters open.
> Another thing it improves is while we're normally waiting for the compaction
> to happen, data that's still coming in will make us go way past the
> MAX_FILESIZE to a point where for the first region I was seeing a store size
> 3-4x bigger before it was able to split.
> I targeted this for 0.94, but I'd like to get this into 0.92.1 or .2 too.
