stack commented on HBASE-10773:
-------------------------------
If we go BR throughout the read path, what happens when we want to move read
blocks from dfsclient to blockcache without bringing the blocks onheap:
http://grepcode.com/file/repo1.maven.org/maven2/org.apache.hadoop/hadoop-common/2.4.0/org/apache/hadoop/fs/HasEnhancedByteBufferAccess.java#HasEnhancedByteBufferAccess
Would that be internal to the blockcache implementation? It could be all BB
but its APIs would be BR based?
> Make use of ByteRanges in HFileBlock instead of ByteBuffers

> Replacing BBs with Byte Ranges in block cache as part of HBASE-10772, would
> help in replacing BBs with BRs in HFileBlock also.
