For any given value being stored into HBase, is accurate to calculate the size

Hello all,
I recently saw some references to zero copy reads in Lars' blog post as well

Is there any additional information available on this topic? I saw some
comments in jira that mentioned the loss of zero copy reads, while others
mention that it's
Perfect thanks, I will run some experiments and keep you posted.
Aside from just getting elapsed time on scans of various sizes, are there any
other tips on what sorts of measurements to perform? Also, since I'm doing the
experiments with various block sizes anyways, any requests for other
Nevermind my last question. I thought BLOCKSIZE was a table attribute but it
