Hi Marco,
Thank you for the idea! It’s not yet on our roadmap but I would love to learn more about your use case.
A Quick lookup in the documentation did tell me that Amazon Timestream supports the JDBC protocol and a subset of SQL statements:
https://docs.aws.amazon.com/timestream/latest/developerguide/supported-sql-constructs.html
https://docs.aws.amazon.com/timestream/latest/developerguide/JDBC.html
This could allow you to connect to Timestream through the Mendix Database Connector (https://marketplace.mendix.com/link/component/2888)
Let me know if this helps you, otherwise feel free to reach out to me via freek.brinkhuis@mendix.com
Hi,
Is there any plan to provide a detailed tutorial on how to connect to Timestream ?
Following the database connector documentation I’m supposed to load the jdbc jar into the userlib directory of my application but several jar’s are available. Which one should be imported ?
I’ve tried all the ones available but always with the following error:
