Melvin Wang commented on CASSANDRA-2819:
----------------------------------------
bq. - currently, expiring map checks callbacks for expiration every 1/2 of
default timeout. This means short timeouts could go much longer than desired,
before being cancelled. I see two options: go back to direct await(timeout) in
the callback/response handlers, or update EM to scan much more frequently
(which could burn a lot of CPU for a system with many outstanding callbacks)
yeah, i guess, calling getReadRpcTimeout/getWriteRpcTimeout explicitly in
ReadCallback/RepairCallback would be simpler and more correct.

> Given the vastly different latency characteristics of reads and writes, it
> makes sense for them to have independent rpc timeouts internally.
