How to check an SFTP Server until the wanted file is available?

Xenoflex — Tue, 07 Feb 2017 14:40:49 GMT

Hi @ll,
I have a problem with waiting for a SFTP file to be available for download.
In Talend I create a file, send it to a secure FTP server. A script processes the file and create a new file for download. The processing time can variate from seconds to minutes.
So after sending the file from Talend to FTP I must wait and check recurring if the new processed file is available for download. Then I could continue the Talend process.
If it would be a localfile, I could check it with the tWaitForFile component, but how can I do it with SFTP?
The only component I found was fFTPFileExist, but I can not build a waiting loop around.
How can I do that?

Kind regards,
Alex

Hi,
Have you tried to build a loop in your work flow?
Here is a TalendHelpCenter:tInfiniteLoop which allows you to execute a task or a job automatically, based on a loop.

Thanks for the hint, I got it. But an example in tInfiniteLoop or tSleep would be nice for new users.
Kind regards,
Alex
