------------------------------------------
Summary: Add a virtual table for exposing batch metrics
Key: CASSANDRA-17225
URL: https://issues.apache.org/jira/browse/CASSANDRA-17225
Project: Cassandra
Issue Type: Improvement
Components: Feature/Virtual Tables
Reporter: Benjamin Lerer
Assignee: Benjamin Lerer
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}}.
