Hello, I created a custom server socket source in which opened server socket in split enumerator, source parallelism is =2 and it gives error while running - “Address is already in use” i.e. it tried to open two server sockets as per parallelism which is not correct as parallelism is applicable for source operator and not for split enumerator?
Please correct me if above understanding is not correct.

The SplitEnumerator is contained in the SourceCoordinator. They are only used in JM.

I looked at the link for custom data sources, one query here that how to make sure for Split enumerator to execute on Job Manager rather than at Task manager?

If you need this connector, you can try to implement it refer to the FLIP-27 source docs [1] https://nightlies.apache.org/flink/flink-docs-master/docs/dev/datastream/sources/ Best, Ron Shammon FY <zjur...@gmail.com<mailto:zjur...@gmail.com>> 于2023年7月27日周四 11:23写道： I cannot find any information about netty source in flink website and it is not in the connector list[1], so I'm think that it is not supported by flink community [1] https://nightlies.apache.org/flink/flink-docs-master/docs/connectors/datastream/overview/ Best, Shammon FY On Thu, Jul 27, 2023 at 10:53 AM Kamal Mittal <kamal.mit...@ericsson.com<mailto:kamal.mit...@ericsson.com>> wrote: Hello Shammon, Yes socket text stream I am aware of but was thinking if something like as ‘https://github.com/apache/bahir-flink/tree/master/flink-connector-netty<https://protect2.fireeye.com/v1/url?k=31323334-501d5122-313273af-454445555731-ffc853ff875d9ed3&q=1&e=30c3fa9e-7c08-4486-8017-0d78c3c714ac&u=https%3A%2F%2Fgithub.com%2Fapache%2Fbahir-flink%2Ftree%2Fmaster%2Fflink-connector-netty>’ is also supported by Flink?
