Download Cassandra JDBC Driver
What Is a JDBC Driver?
A JDBC driver is a Java library file (.jar) that enables Java applications to communicate with a database. The JDBC is a standard interface implemented by each database with a specific driver. Drivers are typically distributed by the database vendor or as open-source projects.
Understanding the JDBC URL
The connection parameters including the database location, database name and connection method are passed to the driver using the JDBC URL. The JDBC URL is a text starting with 'jdbc:...' which combines the hostname, port, database name, and any driver-specific parameters. The exact syntax can be different for each JDBC driver.
The Cassandra JDBC Driver
Apache Cassandra is a highly scalable, distributed NoSQL database designed for high availability with no single point of failure. It uses a wide-column data model and is ideal for write-intensive workloads, time-series data, and globally distributed applications.
For connecting to Cassandra we wrote our own open-source JDBC driver, available on GitHub.
The Apache Cassandra JDBC URL
- Required File(s): cassandra-driver.jar
- Java Driver Class: com.dbschema.Cassandra.JdbcDriver
- JDBC URL: jdbc:cassandra://host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[keyspace];dataCenter[&options]]
- Website: DbSchema.com
The driver is written on top of the native Cassandra Java Driver. For connecting to multiple hosts you can pass an URL like: jdbc:cassandra://host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[keyspace];dataCenter[&options]]
Find the DataCenter using nodetool status or nodetool -h ::FFFF:127.0.0.1 status
Connecting to Cassandra with SSL
Connecting using SSL is possible setting the parameters:
javax.net.ssl.trustStore=/path/to/client.truststore&javax.net.ssl.trustStorePassword=password123&
javax.net.ssl.keyStore=/path/to/client.keystore&javax.net.ssl.keyStorePassword=password123
These parameters can be also set in DbSchema.vmoptions file in the installation folder or ./DbSchema.app/Contents/vmoptions.txt on Mac OS, and add:
-Djavax.net.ssl.trustStore=/path/to/client.truststore
-Djavax.net.ssl.trustStorePassword=password123
# If you're using client authentication:
-Djavax.net.ssl.keyStore=/path/to/client.keystore
-Djavax.net.ssl.keyStorePassword=password123
Downloading the Cassandra JDBC Driver
Download Cassandra JDBC Driver
The driver archive is a zip file. Unzip the downloaded archive to get the driver files. The driver source code can be found on GitHub repository. Check the GitHub link for details on how to use the driver and configure SSL.
The driver is written on top of the standard DataStax Java driver.
DbSchema and Apache Cassandra
DbSchema's open-source Cassandra JDBC driver maps keyspaces and tables into a visual schema explorer. Use DbSchema to browse partition keys, clustering columns, and secondary indexes, and to run CQL queries through the SQL editor interface.
Test the JDBC Driver using DbSchema
Get to your first ER diagram in minutes. No account, no credit card.
Install DbSchema in minutes
DbSchema is free. Download the installer for Windows, macOS, or Linux and start DbSchema. No signup required.
Connect or open a sample
Reverse engineer an existing database or open a sample model to explore tables, relations, and indexes visually.
Design, document, deploy
Edit your schema, generate interactive documentation, and roll out reviewed changes across environments.
Explore Cassandra Visually with DbSchema
Once the JDBC driver is configured, DbSchema connects to your Cassandra database and gives you a full graphical workbench — no command-line required. Available as a free Community Edition and a full-featured PRO Edition. No registration needed to get started.
Interactive ER Diagrams
Reverse-engineer your Cassandra schema into a drag-and-drop ER diagram. Arrange tables visually, add new columns, define foreign keys, and let DbSchema generate the DDL — all without writing SQL by hand.
Visual Query Builder
Compose Cassandra queries by clicking on tables and columns — no SQL knowledge required. Add joins, filters, groupings, and aggregations through a point-and-click interface, then copy the generated SQL or run it directly against the live database.
Relational Data Explorer
Browse Cassandra table data and follow foreign key relationships across tables in a single view. Edit cells inline, filter rows, and paginate through large datasets — all without leaving the explorer.
Schema Synchronization
Compare your Cassandra schema across development, staging, and production environments. DbSchema generates the exact ALTER statements needed to close the gap and lets you review every change before executing — reducing the risk of unintended schema drift.
SQL Editor
Write and execute Cassandra queries in the integrated SQL editor with schema-aware autocomplete, syntax highlighting, and instant result display. Run scripts, inspect execution plans, and export results to CSV or JSON from a single interface.
HTML Schema Documentation
Generate a static HTML site documenting every table, column, type, index, and relationship in your Cassandra schema. Share it with your team or embed it in your project wiki — no extra tooling required.
