BaseX in AWS Lambda - has anyone tried it?

Good afternoon, I’m currently working on a project where I get lots - maybe thousands - of XML files and I have to run a series of tests on them. I get a whole batch then maybe none for a week. I have all my code in XQuery in BaseX but with some locking and update issues it can take a long time to process. So I thought I might give AWS Lambda a try as all the tests can run independently. Before I jump in I wondered if anyone else has tried it? Any thoughts, suggestions, issues? I did a search of the list but didn’t see anything. Many thanks, James
