Add a filter that randomly included rows based on a configured chance.
----------------------------------------------------------------------
Key: HBASE-2824
URL: https://issues.apache.org/jira/browse/HBASE-2824
Project: HBase
Issue Type: New Feature
Components: filters
Reporter: Ferdy
Priority: Minor
We needed a filter that allows us to randomly include rows. I will attach a
patch with a simple Filter that is able to do this.
For example, if you wish to do a scan but only want 1/4 of all values (randomly
distributed), you can use: new RandomRowFilter(0.25f)
I just wanted to share this Filter with you. It's up to you if you want to
include it in the codebase.
