Edward Bortnikov commented on HBASE-16421:
------------------------------------------
Thanks [~anastas], [~anoop.hbase] and [~stack]. Two questions:
1. What is the time frame of this feature? Looks like the full-fledged
implementation + evaluation will take a few months. Can it be candidate for 2.0
then?
2. I guess many of the potential performance concerns are similar to the
read-path off-heaping. There too, Cell objects are created from off-heap block
indexes. Theoretically, there too, it would be desirable to copy the result
directly to the response protocol buffer. Do you think that the read-path
performance would be a good predictor to what we'll see here? What would be the
minimum PoC?
