Jun Rao commented on CASSANDRA-629:
-----------------------------------
The last sentence of TODO above AES.validator.add() is confusing. Other than
that, the patch looks good to me.
Also, don't forget to add a comment saying that hash of inner nodes in Merkle
tree are calculated on demand.
> antientropyservice patchset nearly doubles compaction time

> CompactionsTest goes from 2.9s to 5.7s for me, before/after the 193 patchset.
> This is not an acceptable speed hit for when no repair work is actually
