Aleksey Yeschenko commented on CASSANDRA-10323:
-----------------------------------------------
It's possible to do that quite efficiently now that CASSANDRA-9673 is in.
Commented about it

That's metrics. Batchlog however is not a mechanism for achieving quorum writes
and shouldn't be seen as such.

>
> We need to add more metrics to help understand where time is spent in
> materialized view writes. We currently track the ratio of async base -> view
> mutations that fail.
> We should also add
> * The amount of time spent waiting for the partition lock (contention)
> * The amount of time spent reading data
> Any others?
