----------------------------------
Summary: PyFlink supports closing loop back server
Key: FLINK-30258
URL: https://issues.apache.org/jira/browse/FLINK-30258
Project: Flink
Issue Type: Improvement
Components: API / Python
Affects Versions: 1.16.0
Reporter: Xuannan Su
Currently, a loopback server will be started whenever a
StreamExecutionEnvironment or StreamTableEnvironment is created. The loopback
server can only be closed after the process exit. This might not be a problem
for regular uses where only one environment object is used.
However, when running tests, such as the unit tests for PyFlink itself, as the
environment objects are created, the process starts more and more loopback
servers and takes more and more resources.
