Subject [jira] [Commented] (HBASE-13387) Add ByteBufferedCell an extension to Cell
Date Wed, 08 Jul 2015 09:32:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14618287#comment-14618287
] 

Anoop Sam John commented on HBASE-13387:
----------------------------------------

bq.the name of the second API can be changed ? createFirstOnRowColTS or something like that?
I thought it is implicit mean when we pass the  ts also.. If u strongly feel so, I can change
it on commit.
bq.So for now you are passing the array part alone to the Fake keys? and not the BB based
API? The Fake Cells does not override the Bufferedcell? Later improvement? This fake key changes
decide on what we will do with the blooms and the hashes.
Ya later if needed..

> 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)
