------------------------------------------
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}}.
