Cassandra Connector Release Notes

Support Category: Select

Anypoint Connector for Cassandra provides the capability to connect a Mule app to a Cassandra database or cluster.

Guide: Cassandra Connector User Guide

5.0.0

September 21, 2026

What’s New

  • This connector now supports Apache Cassandra 5.x. The connector now uses DataStax Java Driver 4.17.0.

  • The Cassandra Cluster Name field is removed from Studio. It no longer appears on the General or Advanced Settings tab. Applications that still set clusterName on cassandra-db:connection fail to deploy. Delete the attribute. Contact points and Cassandra Cluster Nodes still select the cluster.

  • The new Local Datacenter field is on the Advanced Settings tab. It sets the local datacenter for the driver’s load-balancing policy. Set this field when contact points don’t share one datacenter, such as in a multi-DC cluster. You can omit it for single-DC clusters.

  • The new Request Timeout (ms) field is on the Advanced Settings tab. It sets the per-request timeout for CQL operations. The default is 12000 milliseconds, which preserves the 12-second deadline from version 4.1.

  • TLS configuration now applies to the driver. The default Endpoint identification algorithm is DISABLED. If your XML still sets HTTPS or LDAPS, version 5.0 validates the server certificate against the host.

  • Don’t select native protocol V1 or V2. Those values fail at application initialization. Leave Protocol Version unset to let the driver negotiate, including native protocol V5 on Apache Cassandra 5.x.

  • On Apache Cassandra 5.x, the Change Column Type operation fails because Cassandra no longer supports altering column types. Add a new column, backfill the data, then drop the old column.
