Reid Chan commented on HBASE-25082:
-----------------------------------
Occasionally bump in, and just an ask: for the append size why don't we use
SizeHistogram but Counter. The latter will accumulate the value only
> Per table WAL metrics: appendCount and appendSize

> 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.
