>                 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'm missing something and it is much harder
to implement than I think?
