Subject [jira] [Commented] (HBASE-10750) Pluggable MemStoreLAB
Date Mon, 17 Mar 2014 08:48:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13937557#comment-13937557

Anoop Sam John commented on HBASE-10750:
----------------------------------------

Allocation is a wrapper of over the byte[] allocated and offset where we want o start write.
 Now the BR can have an offset within itself. So Allocation object as such wont be needed.

> This can allow one to have offheap MSLAB also. 
> The allocate() returns a byte[] now. This has to be changed to ByteRange so that the
impl can return on heap byte[] backed BR or offheap buffer backed BR.
