Hi everyone, Organisation is running Cassandra for Windows v2.2.5 One of our development (non-load testing) clusters has a total of 6 nodes across two DCs, with an RF = 3:3. Each node has a total of 16GB of memory, and no JVM options have been modified.
We're seeing what I believe to be unusually high usage of survivor space across all nodes in the cluster. Some sit at a consistently 100% maxed out state, while others are found at about 90%. Initial thoughts is this is linked to high number of keyspaces/column families running on this particular cluster. There is a total of 28 keyspaces and 412 column families. I have no empirical evidence to support this theory, hence me reaching out to the mailing list. Is there any way to verify this theory, and/or discover potential root causes? Please let me know what other information I can provide, and I'll be sure to get it ASAP. Kindest regards, Daniel Kleviansky
