Importing and Exporting Jobs

Scenario

The FlinkServer web UI enables you to import and export jobs, UDFs, stream tables, and dependencies only.

  • Jobs, flow tables, and UDFs with the same name cannot be imported to the same cluster.
  • When exporting a job, you need to manually select the stream tables, UDFs, and dependencies. Otherwise, a dialog box indicating that the dependent data is not selected will be displayed. The application information of a job will not be exported.
  • When you export a stream table, the application information on which the stream table depends will not be exported.
  • When you export UDFs, the application information on which the UDFs depend and information about jobs used by UDFs will not be exported.
  • When you export dependencies, the application information required by the dependencies and information about the jobs used by the dependencies will not be exported.
  • Data import and export between different applications. are supported.

    When you import or export FlinkSQL jobs, the password field in the jobs will be left blank to meet security requirements. Before you submit jobs, manually enter the password.
