Last Updated:Sep 12, 2024

After you edit the deployment code and click Deploy on the SQL Editor page in the console of fully managed Flink to deploy a draft, fully managed Flink automatically generates a new version for the deployment of the draft. When you edit a deployment, you can compare the current version with an earlier version. After you compare the versions, you can determine whether to roll back the current deployment information to the earlier version.

Background information

Lock a deployment version

The system supports a maximum of 50 deployment versions. If the number of deployment versions exceeds 50, the system automatically deletes the earliest version. You can lock a specific version to ensure that the version is not automatically deleted.

    After the version is locked, a message that indicates the version is locked appears in the upper part of the page, and the 锁 icon is displayed next to the version.

    Note

    If you want to delete a locked version, you must first unlock the version. To unlock the version, choose More > Unlock in the Actions column.
