Node configuration guide states the following:
memtable_flush_queue_size
(Default: 4) The number of full memtables to allow pending flush, that is, waiting for a writer thread. At a minimum, set to the maximum number of secondary indexes created on a single column family.
Does this mean if I have a column family that indexes 20 columns , my memtable_flush_queue size needs to be increased to 20 minimum?
