> Key: FLINK-32863
> URL: https://issues.apache.org/jira/browse/FLINK-32863
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Web Frontend
> Affects Versions: 1.17.1
> Reporter: Runkang He
> Priority: Major
>
> This an UI improvement for OLAP jobs.
> OLAP queries are generally small queries which will finish at the seconds or
> milliseconds, but currently the time precision displayed is second level and
> not enough for OLAP queries. Millisecond part of time is very important for
> users and developers, to see accurate time, for performance measurement and
> optimization. The displayed time includes job duration, task duration, task
> start time, end time and so on.
> It would be nice to improve this for better OLAP user experience.
