Problem Description

When upgrading the FLINK master JAR package or changing startup parameters, you need to re-import the job. Currently, streamis cannot import the latest application configurations online for flink applications that are already running, so you need to kill the application before the import. For applications that consume a large amount of TPS, consumption accumulation or meltdown will occur during the re-import process of kill application.
In addition, the streamis does not have version management for the application configuration. If the application starts abnormally after the configuration is updated, the application configuration of the previous version cannot be quickly rolled back.

Description

streamis application configuration initialization supports online application import and takes effect after restart.
streamis application configurations and user-defined parameters can be modified online and take effect after restart.
