Re: Any basic documentation about using filters with hbase?

I'm afraid that there is a paucity of documentation on filters (to be addressed in upcoming releases): http://people.apache.org/~stack/hbase-0.20.0-candidate-3/docs/api/org/apache/hadoop/hbase/filter/package-summary.html#package_description The principals though need little by way of documentation
