Subject Re: question on column families
Date Wed, 14 Nov 2018 03:09:33 GMT
No, Every column family has its own memstore. Each one is 128MB in your
case. When flushing, the flusher will choose those memstore who satisfy
certain conditions, so it is possible that not every column family(Store)
will flush the memstore.
