According to the documentary group it was hand drawn:

No query planner whatsoever. In databases like XTDB, the order of :where clauses doesn't matter since the engine is able to optimize them. In Datomic, swapping two :where clauses can transform a 10ms query into a 10s query.

Datomic has query-stats https://docs.datomic.com/reference/query-stats.html

I think we just fixed that one. Sorry for the hiccups!

Thanks for the report! just fixed the link.

Interestingly, once you are on datomic you have a little more freedom of choice on underlying storage. Since Datomic uses postgres/ddb/cassandra as just a KV store it becomes trivial to switch underlying storage using the backup and restore feature. Nice if you decide to shop around or like a particular feature of a storage offering.

You will no longer be able to renew Starter after the 1 year period on the same account. Renewal only covers the ability to use newer versions and upgrade. The license is perpetual and as long as you are not upgrading versions -- you will be able to continue using your Starter license.

As was discussed in Datomic Slack:

"Starter was always intended as a path for customers to explore and use Datomic in a low-risk, low-cost approach as they developed their applications and moved toward production. We feel that a year is generally sufficient time to evaluate a product and develop a business application around that product. If you feel that you require a longer period to evaluate or develop against Datomic, please contact us."
