Mikhail Bautin commented on HBASE-5313:
---------------------------------------
[~jdcryans]: I'm OK with reverting HBASE-5521 because it does not look like
HBASE-5313 is moving forward.
> Restructure hfiles layout for better compression

> A HFile block contain a stream of key-values. Can we can organize these kvs
> on the disk in a better way so that we get much greater compression ratios?
> One option (thanks Prakash) is to store all the keys in the beginning of the
> block (let's call this the key-section) and then store all their
> corresponding values towards the end of the block. This will allow us to
> not-even decompress the values when we are scanning and skipping over rows in
> the block.
> Any other ideas?
