--------------------------------------
Thanks [~zjureel], for creating this umbrella, and more importantly for sharing
the experiences and contributing the improvements from ByteDance's internal
practices in Flink OLAP.

> Key: FLINK-25318
> URL: https://issues.apache.org/jira/browse/FLINK-25318
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination, Runtime / Network
> Affects Versions: 1.14.0, 1.12.5, 1.13.3
> Reporter: Shammon
> Priority: Major
> Labels: Umbrella
> Fix For: 1.15.0

> We use flink to perform OLAP queries. We launch flink session cluster, submit
> batch jobs to the cluster as OLAP queries, and fetch the jobs' results. OLAP
> jobs are generally small queries which will finish at the seconds or
> milliseconds, and users always submit multiple jobs to the session cluster
> concurrently. We found the qps and latency of jobs will be greatly affected
> when there're tens jobs are running, even when there's little data in each
> query. We will give the result of benchmark for the latest version later.
> After discussed with [~xtsong], and thanks for his advice, we create this
> issue to trace and manager Flink OLAP related improvements. More users and
> developers are welcome and feel free to create Flink OLAP related subtasks
> here, thanks
