Introduction to Datomic

Datomic is a new database with a flexible schema that keeps a history of all changes, allows you to assign arbitrary attributes to entities and considers the database to be a value.

More buzzwords: ACID transactions, client-side query, elastic scaling, pluggable storage, datalog for queries.

It's similar to git, in that it doesn't forget, but that's more or less where the similarities end: Datomic has a linear history and cares about entities with attributes, not about changes/arbitrary contents.

Examples
