> Key: HBASE-2188
> URL: https://issues.apache.org/jira/browse/HBASE-2188
> Project: Hadoop HBase
> Issue Type: Improvement
> Reporter: Jean-Daniel Cryans
> Priority: Minor
>
> In the same spirit as group commit down in HLog, incrementColumnValue should
> be grouping all requests waiting on the row lock into one in HRegion. This
> means that 10 clients waiting on the lock should be all summed up and then
> applied only once.
