shouweikun opened a new pull request #13789:
URL: https://github.com/apache/flink/pull/13789
…n blink planner
## What is the purpose of the change
- Implement `ParallelismProvider` for sink in blink planner
- `SinkFunctionProvider` and `OutputFormatProvider` work with
`ParallelismProvider` by implementing `ParallelismProvider`
- Prepare for the future work that make all the classes that implements
`SinkRuntimeProvider` currently using in all kind of existing connectors
implement `ParallelismProvider` in order to configure the sink parallelism
## Brief change log
- `CommonPhysicalSink` : get parallelism from `ParallelismProvider` if
possible and configure the sink parallelism into sink transformation after
validation
- `SinkFunctionProvider`: implements `ParallelismProvider`, add factory
method to work with parameter called **parallelism** to set the specified sink
parallelism
- `OutputFormatProvider`: implements `ParallelismProvider`, add factory
method to work with parameter called **parallelism** to set the specified sink
parallelism
- Add necessary tests and helper class for testing the new code mentioned
above
## Verifying this change
This change added tests and can be verified as follows:
- Add helper class `InternalDataStreamSinkProviderWithParallelism` for
the convenience of testing `DataStreamSinkProvider` working with
`ParallelismProvider`
- Add new field: `@Nullable` parallelism in `TestValuesTableSink` for the
test related to `ParallelismProvider` in sink
- Exception is expected if `DataStreamSinkProvider` work with
`ParallelismProvider`
- Test `SinkFunctionProvider` working with `ParallelismProvider`
- Test `OutputFormatProvider` working with `ParallelismProvider`
