---------------------------------
Summary: Add benchmarks for DefaultScheduler#startScheduling (was: Add a
benchmark for DefaultScheduler#startScheduling)
> Add benchmarks for DefaultScheduler#startScheduling
> ---------------------------------------------------
>
> Key: FLINK-21731
> URL: https://issues.apache.org/jira/browse/FLINK-21731
> Project: Flink
> Issue Type: Improvement
> Components: Benchmarks, Runtime / Coordination
> Affects Versions: 1.13.0
> Reporter: Zhilong Hong
> Priority: Major
> Fix For: 1.13.0
>
>
> We notice that {{DefaultScheduler#allocateSlotsAndDeploy}} is not covered in
> the current scheduler benchmark. When we are trying to implement a benchmark
> related to this procedure, we think that it's better to implement a benchmark
> that covers the entire {{DefaultScheduler#startScheduling}} procedure instead.
> This can avoid missing any parts that may affect the performance of
> scheduling. Also in this way we don't need to add benchmarks for every
> sub-procedure related to scheduling, which makes the benchmark heavy and hard
> to maintain. Then we can just focus on the performance-sensitive procedures,
> as the existing benchmarks do.
> The new benchmark item is implemented based on
> {{DefaultSchedulerBatchSchedulingTest}}.
