manually compact memstores?
---------------------------
Key: HBASE-3411
URL: https://issues.apache.org/jira/browse/HBASE-3411
Project: HBase
Issue Type: Brainstorming
Components: regionserver
Reporter: Todd Lipcon
Attachments: hbase-3411.txt
I have a theory and some experiments that indicate our heap fragmentation
issues has to do with the KV buffers from memstores ending up entirely
interleaved in the old gen. I had a bit of wine and came up with a wacky idea
to have a thread which continuously defragments memstore data buffers into
contiguous segments, hopefully to keep old gen fragmentation down.
It didn't seem to work just yet, but wanted to show the patch to some people.
