> Apache Flink: Process to restore more than one job on job manager startup
> from the respective savepoints
> --------------------------------------------------------------------------------------------------------
>
> Key: FLINK-33944
> URL: https://issues.apache.org/jira/browse/FLINK-33944
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Checkpointing
> Affects Versions: 1.18.0
> Reporter: Vijay
> Priority: Major
>
>
> We are using Flink (1.18) version for our Flink cluster. The job manager has
> been deployed in "Application mode" and we are looking for a process to
> restore multiple jobs (using their respective savepoint directories) when the
> job manager is started. Currently, we have the option to restore only one job
> while running "standalone-job.sh" using the --fromSavepoint and
> --allowNonRestoredState. However, we need a way to trigger multiple job
> executions via Java client (from its respective savepoint location) on
> Jobmanager startup.
> Note: We are not using a Kubernetes native deployment, but we are using k8s
> standalone mode of deployment.
> Additional Query: If there is a process to restore multiple jobs from its
> respective savepoints on "Application mode" of deployment, is the same
> supported on Session mode of deployment or not?
> *Expected process:*
> # Before starting with the Flink/application image upgrade, trigger the
> savepoints for all the current running jobs.
> # Once the savepoints process completed for all jobs, will trigger the scale
> down of job manager and task manager instances.
> # Update the image version on the k8s deployment with the update application
> image.
> # After image version is updated, scale up the job manager and task manager.
> # We need a process to restore the previously running jobs from the
> savepoint dir and start all the jobs.
