Cassandra & DataStax Enterprise Essentials

Cassandra & DataStax Enterprise Essentials

This guide shows you how to install and set up a single-node cluster on Cassandra or DataStax Enterprise for evaluation. It also contains an introduction to CQL (Cassandra Query Language), DevCenter (a visual query IDE for creating and running CQL), and basic Cassandra concepts and data modeling considerations.

This document introduces the latest versions of Cassandra, DataStax Enterprise, and OpsCenter. It shows you how to install and set up a single-node cluster for evaluation. Additionally, it introduces CQL (Cassandra Query Language) and DevCenter (a visual query IDE for creating and running CQL), basic Cassandra concepts and data modeling considerations.

Note: For information about setting up a production cluster, see the Cassandra 2.1 or DataStax Enterprise documentation. DataStax 4.7 uses Cassandra 2.1.

Products

  • DataStax Enterprise delivers Apache Cassandra in a database platform that meets the performance and availability demands of Internet-of-Things (IoT), Web, and Mobile applications. It provides enterprises a secure, fast, always-on database that remains operationally simple when scaled in a single data center or across multiple data centers and clouds.
  • Apache Cassandra is a massively scalable open source NoSQL database. Cassandra is perfect for managing large amounts of data across multiple data centers and the cloud. Cassandra delivers continuous availability, linear scalability, and operational simplicity across many servers with no single point of failure, along with a powerful data model designed for maximum flexibility and fast response times.
  • DataStax OpsCenter is a visual management and monitoring solution for Apache Cassandra and DataStax Enterprise. It simplifies administration tasks such as adding and expanding clusters, configuring nodes, viewing performance metrics, rectifying issues, and monitoring the health of your clusters on the dashboard.

    OpsCenter is available for both open source Cassandra and DataStax Enterprise. Different features are available depending on licensing.

  • DevCenter is a free visual query IDE for creating and running CQL statements against Apache Cassandra and DataStax Enterprise.
  • DataStax certified drivers are modern, feature-rich and highly tunable Java client libraries for Apache Cassandra (1.2+) and DataStax Enterprise (3.1+). Use drivers in production applications to pass CQL statements from the client to a cluster and retrieve, manipulate, or remove data.
