@francoiswirion: I've used that approach (two attributes) successfully

@madvas and I were wondering what is the cheapest way to host datomic? Say we have a hobby project, very small and hosted on heroku. I heard datomic free cannot be host on separated server.

(And heroku resets every 24 hours so we can't host datomic free there...)

Much thanks in advance!

Just found https://github.com/colinrymer/docker-datomic-free/blob/master/README.md would you recommend it? Also found free hosting for a docker container here https://cloud.docker.com/

leontalbot: you can try out my alpha hosted transactor service!

Really cool! cc @madvas

Thanks @bvulpes!

Thanks @stuartsierra !

I’m having a heckuva time trying to upgrade my peer to the latest release. I’ve added the necessary dependency for [com.amazonaws/aws-java-sdk-dynamodb “1.9.40”], but when the system is attempting to connect to the transactor, I get a java.lang.NoSuchMethodError: com.amazonaws.services.dynamodbv2.model.AttributeValue.getM()Ljava/util/Map;

I previously was on 0.9.5327, trying to get to 0.9.5350

@jgdavey: Not sure if version issues could be behind it, (1) we have tested and include/suggest version 1.9.39 (documented in the pom.xml provided scope in the datomic distribution), and it could be 1.9.40 introduces (or you have some other) dependency conflict, lein deps :tree might help you troubleshoot (that error looks like it could easily caused by a dependency conflict).

I should have mentioned: 1.9.39 yields the same error. I’ll hunt more for dependency clashes.

I found it. [clj-aws-s3] pulls in [com.amazonaws/aws-java-sdk], which is the whole she-bang.

Thanks for the help, @bkamphaus !
