@whitecoop are you using the same version of Datomic on both peer and the transactor?

Yep. 0.9.5404

Also, you need to set the host property in the transactor properties file to an IP both the peer and transactor can resolve as the transactor machine

I suspect that's the issue

That was it. Fixed once I changed the host property from localhost to the actual IP. Thanks

👍

The transactor.properties file for my ddb storage contains two AWS role properties: aws-transactor-role and aws-peer-role. Are these properties actually used at runtime by the Transactor? I suspect not, since I don't see any AssumeRole priv granted, so I'm guessing these properties are only for the ensure-transactor. Is that correct?

I’m not certain, but that sounds right. datomic by itself doesn’t use or care about AWS roles, the roles should only be used for cloudformation stuff

Roles also provide permissions for things like DDB and S3 access

Datalog question: are namespaced symbols officially supported for rule names ?
