Subject [jira] [Commented] (HBASE-13916) Create MultiByteBuffer
Date Thu, 18 Jun 2015 05:27:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14591276#comment-14591276

stack commented on HBASE-13916:
-------------------------------

But when we call getVlong, are we not positioned at a place form where we can read a vlong?

Or, maybe I am just not getting it. MBB is NOT a BB (because you can't subclass BB). If so,
pardon me.  Move getVlong back to MBB and commit.

> This is an aggregation of N ByteBuffers. The block when served directly by block cache
buckets memory, we have the block data split across multiple byte buffers. This aggregate
type (like ByteBuffer) will serve the HFileBlock data.
> This jira wil just provide the new data structure
