This guide contains simple steps showing how to transact data and run a simple query. However, there are a few topics you might benefit from learning about before you get too far with attempting to use Crux:
EDN – the extensible data notation format used throughout the Crux APIs, see Essential EDN for Crux.
The Datalog query language – Crux supports an EDN-flavoured version of Datalog. The Queries section within this documentation provides a good overview. You can also find an interactive tutorial for EDN-flavoured Datalog here.
Clojure – whilst a complete Java API is provided, a basic understanding of Clojure is recommended – Clojure is a succinct and pragmatic data-oriented language with strong support for immutability and parallelism. See Clojure.org.
Follow the below steps to quickly set yourself up a Crux playground:

For the purposes of this Hello World, we are using the simplest configuration of Crux, where all of the pluggable components are in-memory. There is no Kafka or RocksDB to worry about.

You should get:

An entity query would be:
