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
Could anyone please explain?
