The Datomic Knowledgebase has been launched to provide a place to ask questions, provide answers, discuss and make feature requests.
Datomic Knowledgebase represents our commitment to improve Datomic and Datomic Cloud. It will serve as a place where you can help us prioritize our efforts and help shape the future of Datomic.
With Datomic dev-local you can develop and test applications with minimal connectivity and setup. Get the dev-local library, add it to your classpath, and you have access to the full Client API (both synchronous and asynchronous flavors). This allows you to:
