> Avoid double counting read latencies for digest queries

> Key: CASSANDRA-15058
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15058
> Project: Cassandra
> Issue Type: Bug
> Components: Observability/Metrics
> Reporter: Marcus Eriksson
> Assignee: Marcus Eriksson
> Priority: Normal
> Fix For: 3.0.x, 3.11.x, 4.x
>
>
> We are closing the {{UnfilteredPartitionIterator}} wrapped with
> {{withMetricsRecording}} twice when we get digest requests - closing it calls
> {{onClose}} and that makes the metrics update twice.
