Errors when calling Talend Data Steward API with tRest Component or tDataStewardship components

[stautner_a]

Hi, I have a Talendjob where I call frequently the Talend Data Stewardship API via tRest or tDataStewardship components within an infinite tLoop to do things.

After the job is running for a certain time, sometimes minutes, sometimes hours it breaks with

401, reason phrase: Unable to login to Talend Data Stewardship

or with HTTP 502 Bad Gateway errors.

For me, that looks like that there are request limits, that the job breaks

I studied the documentation for the API, but I didn't find any information about limits there.

So my question are:

• Are there request limits for the Talend Data Steward API?
• If they exist, what are the limits?
• And where do I find the information about the limits?

Thanks for your help.
