Alexey Serbin commented on KUDU-3021:
-------------------------------------
What's missing is the histogram metric to see how big incoming transactions are.
> Add metric gauges for the size of transactions applied to tablets and number
> of rejected transactions due to their size

> Key: KUDU-3021
> URL: https://issues.apache.org/jira/browse/KUDU-3021
> Project: Kudu
> Issue Type: Improvement
> Components: master, tserver
> Reporter: Alexey Serbin
> Priority: Major
> Labels: observability, scalability, troubleshooting
>
> Kudu servers have a limit on the size of transaction applied to a tablet:
> {{\-\-tablet_transaction_memory}}
> It would be nice to introduce corresponding metrics to gauge how relevant the
> current setting is for the actual size of transactions applied in a running
> Kudu cluster. That can help with pro-active tuning of a Kudu cluster to
> sustain a planned increase in workload.
