stack commented on HBASE-11331:
-------------------------------
Looks great to me [~ndimiduk] I am decompressing every time I read from a
block rather than as we have now where we decompress once and that is what is
in the blockcache? Will be interesting to see how this does compared. May
show that this should be optional behavior (we give up CPU here... we need to
start winning it back elsewhere).
> [blockcache] lazy block decompression

> Maintaining data in its compressed form in the block cache will greatly
> increase our effective blockcache size and should show a meaning improvement
> in cache hit rates in well designed applications. The idea here is to lazily
> decompress/decrypt blocks when they're consumed, rather than as soon as
> they're pulled off of disk.
> This is related to but less invasive than HBASE-8894.
