Jonathan Ellis commented on CASSANDRA-3271:
-------------------------------------------
Also: bounds checking for *each byte* seems pretty heavyweight. Feels like
we'd want to add setBytes/getBytes for arrays (that just does one bounds check
outside the inner loop), and update MemoryOutputStream to use that. (I realize
this is not a new problem for the Unsafe Memory per se.)
