[jira] [Created] (CASSANDRA-10323) Add more MaterializedView metrics

T Jake Luciani created CASSANDRA-10323:
------------------------------------------

             Summary: Add more MaterializedView metrics
                 Key: CASSANDRA-10323
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10323
             Project: Cassandra
          Issue Type: Improvement
            Reporter: T Jake Luciani
            Assignee: T Jake Luciani
             Fix For: 3.0.0 rc1


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?
