[jira] [Created] (HBASE-25082) Per table WAL metrics: appendCount and appendSize

Bharath Vissapragada created HBASE-25082:
--------------------------------------------

             Summary: Per table WAL metrics: appendCount and appendSize
                 Key: HBASE-25082
                 URL: https://issues.apache.org/jira/browse/HBASE-25082
             Project: HBase
          Issue Type: Improvement
          Components: metrics
            Reporter: Bharath Vissapragada
            Assignee: Bharath Vissapragada


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.
