This document discusses how to process multiple files sequentially through a file endpoint in Mule. It explains that by default, all files will be processed together in parallel using multiple threads. However, by setting the processingStrategy of the flow to "synchronous", files can be picked up and processed one by one from the inbound folder and dispatched sequentially to the outbound folder. The document provides an example Mule configuration and demonstrates that when multiple files exist in the inbound folder, they will be deposited one by one into the outbound folder over time rather than all at once.
Process file one after another
- 1. By Anirban Sen Chowdhary
- 2. Have you ever thought of processing multiple file sequentially through File endpoint in Mule ?? Generally in a scenario where multiple files exists in the inbound folder, all the files tends to move out together through the file inbound endpoint using multiple thread.
- 3. So, how can we restrict the files in a inbound folder where multiple files exists , to process is a sequential manner , that is the files should be picked one by one and will be dispatched one by one in outbound folder ??
- 4. Let’s see how ….
- 5. Let us consider we designed a flow, a file inbound to pick the file and a file outbound to dispatch the file to outbound folder. Now the reason I kept a Groovy component is to slow the file processing in the flow Now, to configure our file inbound to pick one file at a time is to make the flow processingStrategy="synchronous"
- 6. So, our Mule config will be as follows :- You can see that the inbound endpoint is picking the file from the location :- E:backuptest and putting it into the location E:backuptestnewfolder
- 7. . Now, let’s start out Mule application and deploy it in the server. Let’s keep 5 files in the inbound location as below :-
- 8. . You can see there are 4 file present :- file1.txt, file2.txt, file3.txt, file4.txt in the inbound location as below :-
- 9. . Now, if we move to the outbound location E:backuptestnewfolder , we will find files are getting dispatched one by one as below :- Here file1.txt is deposited first
- 10. . After few millisecond file2.txt is deposited in the same location
- 11. . Now file3.txt is deposited in the same location
- 12. . At the end finally file4.txt get dispatched in the same location Now, you can see all the file has been dispatched one by one in the location.
- 13. So, whenever you need to process one file after another in a sequential manner with file inbound, just configure the flow processingStrategy="synchronous“ And that’s it .. The files will be processed one after another sequentially
- 14. Hope you liked this small tricks in Mule. If you have any similar tricks in Mule, please do share it with all and let our Mule community grow Happy coding
