Subject [jira] [Updated] (HBASE-13387) Add ByteBufferedCell an extension to Cell
Date Tue, 21 Apr 2015 09:07:58 GMT

     [ https://issues.apache.org/jira/browse/HBASE-13387?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Anoop Sam John updated HBASE-13387:
-----------------------------------
    Description: 
This came in btw the discussion abt the parent Jira and recently Stack added as a comment
on the E2E patch on the parent Jira.
The idea is to add a new Interface 'ByteBufferedCell'  in which we can add new buffer based
getter APIs and getters for position in components in BB.  We will keep this interface @InterfaceAudience.Private.
  When the Cell is backed by a DBB, we can create an Object implementing this new interface.

The Comparators has to be aware abt this new Cell extension and has to use the BB based APIs
rather than getXXXArray().  Also give util APIs in CellUtil to abstract the checks for new
Cell type.  (Like matchingXXX APIs, getValueAs<type> APIs etc)

This came in btw the discussion abt the parent Jira and recently Stack added as a comment
on the E2E patch on the parent Jira.
The idea is to add a new Interface 'ServerCell'  in which we can add new buffer based getter
APIs, hasArray API etc.  We will keep this interface @InterfaceAudience.Private

Also we have to change the timestamp and seqId on Cells in server side. We have added new
interfaces SettableSequenceId, SettableTimestamp for this. Now if we can add a ServerCell
we can add the setter APIs there.
