/**
* Provides row-level filters applied to HRegion scan results during calls to
* {@link org.apache.hadoop.hbase.client.ResultScanner#next()}.
Filters run the extent of a table unless you wrap your filter in a
{@link org.apache.hadoop.hbase.filter.WhileMatchFilter}.
The latter returns as soon as the filter stops matching.
Do not rely on filters carrying state across rows; its not reliable in current
hbase as we have no handlers in place for when regions split, close or server
crashes.
