We recently had a lot of OOM in C* and it was generally happening during startup. We took some heap dumps but still cannot pin point the exact reason. So, we need some help from experts.
Our clients are not explicitly deleting data but they have TTL enabled. C* details: > show version [cqlsh 5.0.1 | Cassandra 2.2.9 | CQL spec 3.3.1 | Native protocol v4] Most of the heap was allocated was the object[] - org.apache.cassandra.db.Cell Heap dump images: Heap usage by class: https://pasteboard.co/IRrfu70.png Classes using most heap: https://pasteboard.co/IRrgszZ.png Overall heap usage: https://pasteboard.co/IRrg7t1.png What could be the reason for such OOM? Something that we can tune to improve this? Any help would be much appreciated. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@cassandra.apache.org For additional commands, e-mail: user-h...@cassandra.apache.org
