In Mule 4 is there any any way to run the Mule-Batch in synchronous Mode

I have done several projects using mule batch component. Now present case we have a situation where need to dependent on the output produced by the mule batch component.For my case it is creating a file in asynchronous mode which contains the below information.

studentId,Name,Status 1,bijoy,enrolled 2,hari,not_enrolled, 3,piyush,erolled

But as it is running in asynchronous mode could not rely on the data. My question is is there any way to run mule Batch (Mule 4) synchronously?

No, it is not possible to run a Batch synchronously within the flow it is called, by design.

As an alternative you could put the logic that you want to execute after the batch in a separate flow that listens to a VM queue. In the On Complete phase of the batch you can send a message to that VM queue. The listening flow can't receive batch data directly but for a file it should be OK.

Having said that, file exchange is not a very good method of exchanging information inside an application. I would recommend to explore alternatives like databases for transient data, unless you just need the file to send it elsewhere.

  • yes the comment is true . What I have created a mule schedular which triggers a job on every 5 mins and . by using the mule batch component I dump the output on a object store. and from another mule rest api just call the object store . So that I although can't get the real time data but as the mule batch runs in every 5 minutes so that job store is populated with almost updated data and use it. – Biltu - Technology Jan 12 '22 at 19:01
  • that implementation has the issue of may not be concurrent safe. If the batch job needs more that 5 minutes, will it override the previous execution? Also Object Stores have some limitations. If they impact your application will depend on the specific use case. – aled Jan 12 '22 at 19:45
