100% Open Source Compatible

Avoid vendor lock-in with an Apache Cassandra™ distribution that is 100% open source compatible.

Fully Supported

Reduce costs and ensure SLAs are met with support from the Apache Cassandra experts.


Minimize risk and maintenance costs with a Cassandra distribution that’s undergone rigorous QA and testing.

Dashboard Monitoring and Alerting

A DSE monitoring system supplying customizable dashboards with real-time and historical metrics and alerting.

DataStax Studio

DataStax Studio is a visual developer tool that makes it easy for developers to write queries, slice and dice your data through visualizations, and collaborate with teammates in an intuitive notebook-based development environment.

Visualize and Explore Data

Rich data visualizations and numerous output formats enable you to fluidly interact with your data and produce publication-quality graphics.

Syntax Validation and Smart Suggestions

An intelligent code editor ensures that your queries are right the first time through syntax validation and context-aware suggestions.

Advanced Workloads

CQL, Gremlin, and Spark SQL queries can be run side by side for use cases that require Graph and Analytics capabilities.

Collaborate with peers

Share your work with colleagues through the notebook import and export feature.

DataStax Bulk Loader

DataStax Bulk Loader is an efficient, flexible, easy-to-use command line utility that excels at loading, unloading, and counting data. It gets data in and out of the database faster than any other copy commands and community tools. Use it with JSON or CSV files to jump start your application development.


Load from JSON or CSV files to the database.


Unload data stored in the database to JSON or CSV files.


Quickly count the number of rows in a given table.

DataStax Apache Kafka™ Connector

The DataStax Apache Kafka Connector automatically takes records from Kafka topics and writes them to a DataStax database. This sink connector is deployed in the Kafka Connect framework and removes the need to build a custom solution to move data between these two systems.


Flexible mapping to allow reads from many Kafka topics and writes to many DataStax tables, fits nicely to the common denormalization pattern used with Cassandra..


Created by the authors of the DataStax Drivers for Apache Cassandra™ and uses best practices for database writes, resulting in fast data movement.


You have to write zero lines of code if you use the connector to ingest from Kafka to a DataStax database.

DataStax DevCenter

DataStax DevCenter is a free visual schema and query environment to create and run Cassandra Query Language (CQL) statements against Apache Cassandra™ and DataStax Enterprise. Note this tool is End of Service Life and no longer under active development. DataStax customers should use DataStax Studio.

Graph Loader

DSE Graph Loader is a customizable, highly tunable command line utility for loading graph datasets into DSE Graph from various input sources. It is built to load datasets containing hundreds of millions (10^8) of vertices and billions (10^9) of edges. DSE Graph Loader is efficient, using parallel loading and persistent cache to store vertices, provided a sufficient machine is used to run the program.

Multiple Sources Available

Data can be loaded from CSV files, JSON files, delimited text (CSV with a header line to identify the fields), text parsed by regular expressions, and binary Gryo files.


Reads entire input data to check for graph schema conformity. Suggests graph schema updates, or if enabled, changes graph schema. Supplies statistics about how much data will be added to graph when loaded.

Vertex loading

Adds or retrieves all of the vertices in the input data and caches them locally to speed up subsequent edge loading.

Edge and Property Loading

Adds all edges and properties from the input data to the graph.

DataStax Enterprise Drivers

DataStax Drivers for DataStax Enterprise (DSE Drivers) are the client libraries for app developers creating solutions using DataStax Enterprise on-premises or in the cloud. The drivers have all of the functionality of the DataStax Drivers for Apache Cassandra™ as well as additional features for DSE-specific features, including Advanced Security and DSE Graph. For details, reference the documentation.

Popular Programming Languages

DataStax supports C/C++, C#, Java, Node.js, PHP, Python, Ruby, JDBC and ODBC drivers.

Cluster Awareness

The drivers are tightly coupled with the server and they intelligently route and load balance queries, retry when necessary and automatically reconnect after a restart.

Synchronous and Asynchronous APIs

The drivers are built to support high volumes of concurrent requests and offer both synchronous and asynchronous APIs.

Advanced Workloads

The DSE Drivers additionally support DataStax Graph traversals, Advanced Security LDAP/AD/Kerberos, and DSE Geospatial Types.


To connect with individual databases, JDBC (the Java Database Connectivity API) requires drivers for each database. The JDBC driver gives out the connection to the database and implements the protocol for transferring the query and result between client and database.

Since the Open Database Connectivity (ODBC) is such a prolific framework to enable Business Intelligence (BI) tools, DataStax provides a set of ODBC drivers to enable these use cases. For reference on ODBC drivers check out this blog.

DataStax Drivers for Apache Cassandra™

The DataStax Drivers for Apache Cassandra ( OSS Drivers ) are the client libraries for application developers creating solutions using Apache Cassandra on-premises or in the cloud. The OSS Drivers can also be used with DataStax products. For details, reference the documentation.

Popular Programming Languages

DataStax supports C/C++, C#, Java, Node.js, PHP, Python, Ruby and ODBC drivers.

DataStax Labs

DataStax Labs provides the Apache Cassandra™ and DataStax communities with non-supported previews of enhancements that may or may not be included in future DataStax production software, as well as tools, aids, and partner software designed to increase productivity.

So be our guest, have fun with DataStax Labs previews, and try it out. And note our disclaimer that these tools are not supported, and so should not be put into production.

And as you try out some of our new Labs technologies, tools, and experimental features we would love your feedback. Good or bad, let us know!

You can connect with us through the DataStax Community.
“Who better to help us shape our software than our developer community–the engineers that use it every day. We have a lot of ideas, but we want to make sure they make your job easier. Try out some of the cutting-edge builds and let us know.”
– Patrick McFadin, VP Developer Relations, DataStax
DataStax Graph (DSG)

Try out some ideas we have on solving graph problems like the write once/read in any model capability—we hope you find this graph easier to use, plus it’s up to 14x faster!
