I would look into the AWS Services module for S3: https://marketplace.mendix.com/link/component/117958
Also, could you use the DB connector with the Athena JDBC driver? I havent done it personally, but just a thought.
Tried to use the module – AWS Services. But facing lots of problems. First it overwrites the Atlas UI. So downloaded that from MarketPlace. Then it is missing “LibraryLogging.AddLibraryLogListener. Tried to download Library Logging from MarketPlace, but it is not compatible with version 9.8, so could not download. I am kind of lost here. Can you help me.
