Hello!
We have 1.0.7 multi-DC cassandra setup with strict time limits for read
(15ms). We use RF=1 per DC and reads with CL=ONE. Data in datacenters
are in sync, but we have next problem:
when application looks for key which is not yet in database, coordinator
wait for digests from remote datacenters which breaks our time limits.
I know that we can use RF:3 per DC and read with LOCAL_QUORUM to
restrict reads to local DC only, but RF:3 is not acceptable for us.
Can we force somehow cassandra not to lookup keys in remote CD?
Thanks for your answers!
