becketqin opened a new pull request, #25742:
URL: https://github.com/apache/beam/pull/25742
This is the second patch of migrating Flink runner to execute batch jobs
with DataStream API.
This patch does the following:
1. Add a new option of `UseDataStreamForBatch`. When it is set to true, the
batch jobs will be executed with DataStream API. Otherwise, the jobs are
executed with DataSet API.
2. Modify the pipeline translation path to honor the configuration.
3. Modify the tests to cover the DataStream execution path.
This patch should be merged after #25741 is resolved, so the streaming jobs
metrics are still backwards compatible.
fix #25740
