Java Driver for Scylla and Apache Cassandra®¶

If you’re reading this on github.com, please note that this is the readme for the development version and that some features described here might not yet have been released. You can find the documentation for latest version through Java Driver Docs or via the release tags, e.g. 4.12.0.0.

A modern, feature-rich and highly tunable Java client library for Scylla and [Apache Cassandra®] (2.1+), using exclusively Cassandra’s binary protocol and Cassandra Query Language (CQL) v3.

Getting the driver¶

The driver artifacts are published in Maven central, under the group id com.scylladb; there are multiple modules, all prefixed with java-driver-.

<dependency>
  <groupId>com.scylladb</groupId>
  <artifactId>java-driver-core</artifactId>
  <version>${driver.version}</version>
</dependency>

<dependency>
  <groupId>com.scylladb</groupId>
  <artifactId>java-driver-query-builder</artifactId>
  <version>${driver.version}</version>
</dependency>

<dependency>
  <groupId>com.scylladb</groupId>
  <artifactId>java-driver-mapper-runtime</artifactId>
  <version>${driver.version}</version>
</dependency>

Note that the query builder is now published as a separate artifact, you’ll need to add the dependency if you plan to use it.

Refer to each module’s manual for more details (core, query builder, mapper).

Compatibility¶

The driver is compatible with Scylla and Apache Cassandra® 2.1 and higher.

It requires Java 8 or higher.

Migrating from previous versions¶

Java driver 4 is not binary compatible with previous versions. However, most of the concepts remain unchanged, and the new API will look very familiar to 2.x and 3.x users.

See the upgrade guide for details.

Training:¶

The course Using Scylla Drivers in Scylla University explains how to use drivers in different languages to interact with a Scylla cluster. The lesson, Coding with Java Part 1, goes over a sample application that, using the Java driver, interacts with a three-node Scylla cluster. It connects to a Scylla cluster, displays the contents of a table, inserts and deletes data, and shows the contents of the table after each action. The course also includes more advanced lessons that demonstrate working with prepares statements and datatypes.
