Hi We are seeing high response times on the application side from the Java Reactive DSE driver. Cassandra server side metrics show response times of 2 ms but the DSE logs show a response time (95th percentile) of 40ms. Following https://docs.datastax.com/en/developer/java-driver/4.2/manual/core/pooling/ it appears that the connections are open for sometime during a load run and they go to 0, then again open-connections goes to the configured value (4) + 1 and then again to 0. Why is that ? Load run is at 30K RPM. This happens even when I reduce the heartbeat interval to as low as 250 milliseconds. The CPU consumed by the container is just 35% of available.
Can someone help with this ? Thanks -- Shaurya Gupta
