Setting up JanusGraph

Question

I'm new to JanusGraph. Can somebody help me edit this docker-compose file to use ScyllaDB instead of Cassandra and Apache Solr instead of Elasticsearch? Also does Apache Spark get installed automatically or do I have to also put it into the docker-compose file?

Thank you.

Edit: I've successfully switched Cassandra to Scylla

version: "3"

Answer 1

Ok, so Scylla installation is fine now. Regarding Spark, you'll need to install it yourself or add another container for it.
