I am evaluating On-Prem version of Datomic and have been getting below warning messages at Datomic transactors:

No Dead Letter Address configured for queue schematest2-3b27988c-4fca-4e59-aa47-9dcae9e9ad88.tx-result625e9e54-2d49-436e-95b6-b9de541636d5 in AddressSettings
No Expiry Address configured for queue schematest2-3b27988c-4fca-4e59-aa47-9dcae9e9ad88.tx-result625e9e54-2d49-436e-95b6-b9de541636d5 in AddressSettings

A few pointers on how to address these would be very helpful. Are these ActiveMQ settings documented some where at https://docs.datomic.com/on-prem/?

I believe these are deliberate and you are not meant to address them. These are queues set up by datomic itself to communicate tx updates to peers (artemis is considered an implementation detail) to communicate with a peer and it didn’t configure any dead-letter queue for them because it doesn’t make sense to dead-letter these if the peer is gone or can’t be communicated with--the message is the transaction log, and the queue will get it back when it reconnects.
