[jira] [Created] (HBASE-8959) Bitmasks handling

Max Lapan created HBASE-8959:
--------------------------------

             Summary: Bitmasks handling
                 Key: HBASE-8959
                 URL: https://issues.apache.org/jira/browse/HBASE-8959
             Project: HBase
          Issue Type: New Feature
            Reporter: Max Lapan
            Priority: Minor


I think it would be useful to natively support bitmasks in hbase columns with ability to check/set/clear/toggle individual bits in byte[] for any column. 

Now, we forced to store lots of feature flags as separate, 1-byte values, which  is a waste of space. Compression helps, I guess, but anyway, not ideal.

I see this as a set of new KeyValue.Type, which describes needed bit-operations. Operations itself performed on compaction or scan process. Similiar things a performed for KeyValue.Minimum and KeyValue.Maximum. 

What do you think about this feature? Maybe, I missing something and it is much harder to implement than I imagine?
