> Reporter: Bharath Vissapragada

> Priority: Major

>
>
> We were trying to drill down into WAL events at a table scope and figured that appendCount and appendSize are not exposed at a table scope. This would be a helpful metric.
> I ran the WAL benchmark tool with 10 threads and didn't see any measurable performance difference with the attached patch.
