i'd also let get-user take the db as an argument, you can then get the db with the changes from the transaction from the :db-after field

(let [{:keys [db-after]} (db/add-user ...)]
  (r/response (db/get-user db-after "foo"))  

Is it possible to override the S3 endpoint for datomic backup to use it with google cloud storage?

For anyone here wondering about some resources to learn Datomic I have been working hard to put this together — there is still long way to go but definitely a good moment to share https://learndatomic.com

what might be a cause of the following error?

(dl/import-cloud {:source {:server-type :ion
                           :region      "the-region"

This client does not support dev-local import.

It may be possible if you can do it via some magic amazon s3 client override configuration. The last time I looked into this a few years ago there didn’t seem to be a way.

I think cognitect itself could do it fairly easily when they configure the s3 client in their code; but the trick for us is to do it without changing that code

I guess with enough reverse engineering, reflection, and monkey-patching anything is possible
