Junfan Zhang commented on FLINK-25495: -------------------------------------- [~wangyang0918] Thanks for your reply. {noformat} I am afraid that depending on the attach mode is not reliable since the Flink client may disconnect because of network issues or JobManager failover. {noformat} I'm doubt whether the above problems will also occur when in per-job attach mode. > Client support attach mode when using the deployment of application mode > ------------------------------------------------------------------------ > > Key: FLINK-25495 > URL: https://issues.apache.org/jira/browse/FLINK-25495 > Project: Flink > Issue Type: Improvement > Components: Client / Job Submission > Reporter: Junfan Zhang > Priority: Major > > h2. Why > In our internal data platform, we support flink batch and streaming job > submission. To reduce the submission worker overload, we use the Flink > application mode to submit flink job. It's a nice feature! > However, on batch mode, we hope flink client couldn't exit until the batch > application finished (No need to get job result, just wait). Now the flink > lack this feature, and it is not stated in the document that Application Mode > does not support attach. -- This message was sent by Atlassian Jira (v8.20.1#820001)
