Subject Increased Cassandra connection latency
Date Fri, 23 May 2014 10:35:03 GMT
Hi all,

I've noticed increased latency on our tomcat REST-service (average 30ms,
max > 2sec). We are using Cassandra 1.2.16 with official DataStax Java
driver v1.0.3.

Our setup:

* 2 DCs
* each DC: 7 nodes
* RF=5
* Leveled compaction

After cassandra restart on all nodes, the latencies are alright again
(average < 5ms, max 50ms).

Any thoughts are greatly appreciated.

Thanks,
Alexey
