Subject [jira] [Updated] (HBASE-13387) Add ByteBufferedCell an extension to Cell
Date Mon, 06 Jul 2015 04:22:05 GMT

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

Anoop Sam John updated HBASE-13387:
-----------------------------------
    Attachment: benchmark.zip

Attaching the JMH test I have used to check the cost of additional checks into CellComparator.
 When we make ByteBufferedCell as an interface, extending Cell the cost seems much more..
 When we make ByteBufferedCell an abstract class the throughput is similar to that of with
out instance of check compare impl.

> 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)
