Hi - On our recently live cassandra cluster of 5 nodes, we've noticed that the latency readings, especially Reads have gone up drastically.
TotalReadLatencyMicros 5413483 TotalWriteLatencyMicros 1811824 I understand these are in microseconds, but what meaning do they have for the performance of the cluster? In other words what do these numbers actually measure. In our case, it looks like we have a read latency of 5.4 seconds, which is very troubling if I interpret this correctly. Are reads really taking an average of 5 seconds to complete??
