Datastax Java Driver for Apache Cassandra

Travis Build

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. 2.0.10.1.

A modern, feature-rich and highly tunable Java client library for Apache Cassandra (1.2+) and DataStax Enterprise (3.1+) using exclusively Cassandra's binary protocol and Cassandra Query Language v3.

Features:

The driver architecture is based on layers. At the bottom lies the driver core. This core handles everything related to the connections to a Cassandra cluster (for example, connection pool, discovering new nodes, etc.) and exposes a simple, relatively low-level API on top of which higher level layers can be built.

The driver contains the following modules:

  • driver-core: the core layer.
  • driver-examples: example applications using the other modules which are only meant for demonstration purposes.

Community:

Feeback requested: help us focus our efforts, provide your input on the Platform and Runtime Survey (we kept it short).

Maven

The last release of the driver is available on Maven Central. You can install it in your application using the following Maven dependency:

<dependency>
  <groupId>com.datastax.cassandra</groupId>
  <artifactId>cassandra-driver-core</artifactId>
  <version>2.0.10.1</version>
</dependency>

We also provide a shaded JAR to avoid the explicit dependency to Netty.

Compatibility

The Java client driver 2.0 (branch 2.0) is compatible with Apache Cassandra 1.2 and 2.0, but some features are available only when using Apache Cassandra 2.0 (e.g. result set paging, BatchStatement, lightweight transactions -- see What's new in Cassandra 2.0). Trying to use these with a cluster running Cassandra 1.2 will result in an UnsupportedFeatureException being thrown.

Upgrading from 1.x branch

If you are upgrading from the 1.x branch of the driver, be sure to have a look at the upgrade guide.

We used the opportunity of a major version bump to incorporate your feedback and improve the API, to fix a number of inconsistencies and remove cruft. Unfortunately this means there are some breaking changes, but the new API should be both simpler and more complete.

Troubleshooting

If you are having issues connecting to the cluster (seeing NoHostAvailableConnection exceptions) please check the connection requirements.
