Hello! Could you please give some ideas on the following problem?
We have a cluster with 3 nodes, running Cassandra 2.2.11. We've recently discovered high CPU usage on one cluster node, after some investigation we found that number of sstables for one CF on it is very big: 5800 sstables, on other nodes: 3 sstable. Data size in this keyspace was not very big ~100-200Mb per node. There is no such problem with other CFs of that keyspace. nodetool compact solved the issue as a quick-fix. But I'm wondering, what was the cause? How prevent it from repeating? -- Best Regards, Dmitry Simonov
