----------------------------------
Summary: Release Testing: Verify FLIP-283 Use adaptive batch
scheduler as default scheduler for batch jobs
Key: FLINK-31071
URL: https://issues.apache.org/jira/browse/FLINK-31071
Project: Flink
Issue Type: Sub-task
Reporter: Lijie Wang
This task aims to verify [FLIP-283 Use adaptive batch scheduler as default
scheduler for batch jobs|https://issues.apache.org/jira/browse/FLINK-30682].
The documentation of adaptive batch scheduler can be found
[here|https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/elastic_scaling/#adaptive-batch-scheduler]
.
Things to verify:
1. Verify the adaptive batch scheduler is the default scheduler of batch jobs.
By default, Flink will automatically decide parallelism for operators of batch
jobs if the scheduler is not specified.
2. Verify the configuration
options(execution.batch.adaptive.auto-parallelism.xxx) are in effect. Besides,
it is also necessary to verify that the default parallelism set via
parallelism.default or StreamExecutionEnvironment#setParallelism() will be used
as upper bound of allowed parallelism if the
execution.batch.adaptive.auto-parallelism.max-parallelism is not configured.
3. Verify the final data produced are correct.
