Subject [jira] [Commented] (HBASE-15879) Introduce Key interface
Date Thu, 02 Jun 2016 17:24:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15312703#comment-15312703

stack commented on HBASE-15879:
-------------------------------

bq. The intention here was to say that some of the Cell impls are trying to have its key in
a continuous structure and let those cells have this interface. 

The model should not be such that Key only makes sense in case where row is contiguous with
column family and qualifier, etc.

Streamable should be done with Codec?

> Introduce an interface called Key and allow Cell implementations to implement this Key
interface for cases like KeyValue, OffheapKeyValue and DBE cells (Except prefix tree) so that
we can avoid copies when we deal with only Cells in case of block index creations (like ROOT,
Bloom etc). Helps in reduction of garbage also.
