Phantom is a schema-safe, type-safe, reactive Scala DSL and driver for Apache Cassandra and DataStax Enterprise. It lets you define Cassandra tables and queries in Scala with compile-time type checking and pluggable concurrency backends like Scala Futures, Monix, and Twitter Util.

Use cases

• access cassandra from scala with type-safe queries
• define cassandra table schemas in scala code
• run reactive cassandra queries with futures or monix
• build a scala data layer for datastax enterprise
• avoid raw CQL strings when querying cassandra
• manage cassandra schema migrations from scala

When to choose

• you are building a Scala/JVM application backed by Cassandra or DataStax Enterprise
• you want compile-time safety for table schemas and CQL queries
• you need reactive-streams or pluggable concurrency backends for query execution

When to avoid

• your project is not on the JVM or does not use Scala
• you use a database other than Cassandra/DataStax Enterprise
• you need a driver with frequent updates and active community support
