Subject [jira] [Commented] (HBASE-10750) Pluggable MemStoreLAB
Date Sat, 15 Mar 2014 22:58:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13936333#comment-13936333

Andrew Purtell commented on HBASE-10750:
----------------------------------------

bq. When we work with offheap chunks, might be like we can make this also generic (backed
by BR) and avoid some code duplications. Any way leaving it as of now, when coming up with
offheap impl, that also can be done IMO.

Looks good to me, Chunk encapsulates those details.

> 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.
