I am getting dropped mutation due to GC.MY young Generation GC is taking long time
G1 Young Generation GC in 1804ms. G1 Eden Space: 771751936 -> 0; G1 Old Gen: 5351931920 -> 4995416072; G1 Survivor Space: 83886080 -> 58720256;
MUTATION messages were dropped in last 5000 ms: 814 for internal timeout and 0 for cross node timeout. Mean internal dropped latency: 2874 ms and Mean cross-node dropped latency: 0 ms
In order to avoid this should I decrease the MaxGCPauseMillis option in Cassandra-env.sh.
our default value is 500ms.(JVM_OPTS="$JVM_OPTS -XX:MaxGCPauseMillis=500)
Would tuning this setting will reduce the dropped mutation messages. Do I need to increase or decrease the value.
