tDocumentDBOutput - using Set with _id as the Key

ml1662663516 — Fri, 15 Nov 2024 21:27:53 GMT

We are currently converting from Mongo to AWS DocumentDB. I am starting to go through our Talend jobs and swapping out the various Mongo components with DocumentDB components.

So far reading from our database using the tDocumentDBInput is working good.

However, I am running into trouble trying to update our database using a tDocumentDBOutput component.

Specifically, I am not sure I am using the Keys Mapping section of the

tDocumentDBOutput component correctly.

The old Mongo component picked up the key from the schema. However, with the new DocumentDB component, it does not and you are given a Keys Mapping section.

Basically, I am just updating certain records in DocumentDB with a timestamp based on their _id.

I have attached three screenshots.

With the current set up, no records are showing the new timestamp.

This all worked perfectly with Mongo.

Any help is appreciated! Thank you!
