Your batch app crashed two hours into its three-hour run. Now you may have to do some cleanup and then restart it. Do you really have to do this, or can tools do this for me?

In this talk, we show how you can use Spring Batch and workflow engines to rescue a failed batch execution.

This discussion includes examples of how you can use Spring Cloud Data Flow Argo along with Spring Batch to reset and restart an execution without human intervention.

This project contains the samples I used in the presentation and a PDF of the presentation slides.

• batch-testapp - Contains the project that has the batch app showing Spring batches ability to restart a failed batch.

• FilterAndFixProcessor - Contains the project that has a Stream processor that will attempt to resolve the problem that causes batch-testapp to fail

• workflowfix - Contains the project that is used to resolve the batch-testapp’s problem using the Argo workflow

• scripts - Contains the argo workflow yaml file
