Lars Francke reopened HBASE-3879:
---------------------------------
> Add way to control the split position of region
> -----------------------------------------------
>
> Key: HBASE-3879
> URL: https://issues.apache.org/jira/browse/HBASE-3879
> Project: HBase
> Issue Type: Improvement
> Components: regionserver
> Reporter: Ophir Cohen
> Priority: Minor
>
> Currently the split point picked to be the mid key of the HFile.
> From the code comments:
> "Midkey for this file. We work with block boundaries only so
> * returned midkey is an approximation only."
> It could be good to have a way to override the default option and use other
> method.
> Possible implementation:
> Create interface (similar to Hadoop's partitioner) that gets StoreFile /
> StoreFile.Reader and return the splitting point.
