dawidwys opened a new pull request #16351:
URL: https://github.com/apache/flink/pull/16351
## What is the purpose of the change
This PR cleans up StreamOperator API in regards to the termination phase and
introduces a clean finish() method for flushing all records without releasing
resources.
The StreamOperator#close method which is supposed to flush all records, but
at the same time, currently, it closes all resources, including connections to
external systems. We need separate methods for flushing and closing resources
because we might need the connections when performing the final checkpoint,
once all records are flushed. Moreover, the logic for closing resources is
duplicated in the StreamOperator#dispose method.
