Andrew Purtell resolved HBASE-6434.
-----------------------------------
Resolution: Not a Problem
> Document effect of slow compressors on the flush path and workaround in the
> online book
> ---------------------------------------------------------------------------------------
>
> Key: HBASE-6434
> URL: https://issues.apache.org/jira/browse/HBASE-6434
> Project: HBase
> Issue Type: Task
> Reporter: Andrew Purtell
> Priority: Minor
>
> In HBASE-6423 Karthik writes
> bq. 1. flushing a memstore takes a while (GZIP compression)
> [... and the memstore gate comes crashing down]
> We once sidestepped this issue by specifying different compression options
> for flushes (LZO or none) and major compaction (BZIP2), disabling automatic
> major compaction, and managing major compaction from a shell based process
> that iterates over each region on disk and makes some application specific
> decisions.
> I go back and forth on whether this is a hack or legitimate HBase ops given
> how things currently work.
