Cassandra Data Source (CASSANDRA) v25.1+ PREVIEW

The Cassandra data source enables interaction with a Cassandra cluster.

While it shares similarities with other Kubling database data sources, it is not categorized under that group because:

  • Capabilities: The supported query operations and optimizations differ from standard relational databases.
  • Translation Mechanism: The internal query translation process requires a distinct approach for Cassandra.

Due to these differences, Cassandra is handled in Kubling as a separate data source type under the database datasource category.

⚠️

As of version v25.1, only passthrough mode is supported. This means that custom DDL definitions are not yet available. We plan to introduce this capability in a future release, along with support for synthetic tables.

However, you can still define additional columns through the schema configuration.
