             Summary: Add virtual table for exposing prepared statements metrics
                 Key: CASSANDRA-17224
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17224
             Project: Cassandra
          Issue Type: Improvement
          Components: Feature/Virtual Tables, Observability/Metrics
            Reporter: Benjamin Lerer


There are some existing metrics within {{CQLMetrics}} that provide metrics about prepared statements. We should exposed those through a virtual table.

+Additional information for newcomers: +

A new class should be created for representing the new Virtual Table in {{org.apache.cassandra.db.virtual}}. You can look at {{ThreadPoolsTable}} for an example.
The new table will need to be registered in {{SystemViewsKeyspace}}.
Some unit tests will need to be added. For some example of virtual table tests you can look at {{SystemPropertiesTableTest}} and for some example of test around prepared statement metrics you can look into {{CQLMetricsTest}}.
