------------------------------------
Summary: Add a benchmark 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
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}}.
