Dear All,
We met some C* nodes oom during secondary index creation with C* 2.1.18. As per https://issues.apache.org/jira/browse/CASSANDRA-12796,the flush writer will be blocked by index rebuild.but we still have some confusions: 1.not sure if secondary index creation is the same as index rebuild 2.we noticed that the memory table flush looks still working,not the same as CASSANDRA-12796 mentioned,but the compactionExecutor pending is increasing. 3.I'm wondering if the block only blocks the specified table which is creating secondary index? Could anyone please explain? Thanks
