Hi Michael,
I noticed you added a PR. Is it ready for review or you are still working on
it? Also, please, let me know if you want me to run CI for you? If you are
done, please, move the ticket to Patch Available or even better Needs Committer
to trigger the attention of potential reviewers. Thank you!

> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Virtual Tables
> Reporter: Benjamin Lerer
> Assignee: Michael Burman

> There are some existing metrics within BatchMetrics that provide metrics
> about related to the different types of Batches being executed. We should
> expose 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 of virtual table implementation and to {{TableMetricTables}} for
> how Histogram metrics can be exposed. The new table will need to be
> registered in {{SystemViewsKeyspace}}.
> Some unit tests should be added. For some example of virtual table tests you
> can look at {{SystemPropertiesTableTest}}.
