Spring Cloud DataFlow多次运行组合任务

Question

Is there any way to tell Composed task runner (CTR) to run composed task multiple times?

For now, in SCDF 1.2.3.RELEASE and CTR 1.0.0.RELEASE, if particular task in composed task has been completed, CTR doesn't execute it again.

Answer 1

A composed-task is a graph (represented in a DSL) defining a series of steps where each step can be a task or a batch-job. Once the composed-task is launched, it will execute all the steps and its transitions as defined by the DSL.

Unless you schedule the composed-task to launch on the desired frequency (eg, "every 1hr"; "every day at 11p" etc.) , it won't automatically re-execute it. Please consider using a scheduler for this purpose.
