Hi everyone, I would like to start a discussion about FLIP-530: Dynamic job configuration [1].
In some cases, it is desirable to change Flink job configuration after it was submitted to Flink, for example: - Troubleshooting (e.g. increase checkpoint timeout or failure threshold) - Performance optimization, (e.g. tuning state backend parameters) - Enabling new features after testing them in a non-Production environment. This allows to de-couple upgrading to newer Flink versions from actually enabling the features. To support such use-cases, we propose to enhance Flink job configuration REST-endpoint with the support to read full job configuration; and update it. Looking forward to feedback.
