Jepsen: Datomic Pro 1.0.7075
Background Datomic is a general-purpose database intended for systems of record. In many ways, Datomic is unusual.
Datomic’s in-transaction conflict checker did not prevent this behavior because the approve and deny functions returned assertion requests for disjoint[entity, attribute] pairs. You can use them to ensure atomic read-modify-update processing, and integrity constraints… A transaction function can issue queries on the db value it is passed, and can perform arbitrary logic in the programming language. Jepsen wishes to thank the entire Datomic team at Nubank, and in particular Dan De Aguiar, Guilherme Baptista, Adrian Cockcroft, Stuart Halloway, Keith Harper, and Chris Redinger.
