Re: [jira] Updated: (HBASE-1197) IPC of large cells should transfer in chunks not via naive full copy

With HFile there should ideally be only 1 copy of the key/value in memory,
and whatever mechanism can chunk off the ByteBuffer without overly
duplicating data.  This might help with this problem some.
