Apache Cassandra connection

To access your data in Apache Cassandra, create a connection asset for it.

Apache Cassandra is an open source, distributed, NoSQL database.

Supported versions

Apache Cassandra 2.0 or later

Create a connection to Apache Cassandra

To create the connection asset, you need these connection details:

  • Hostname or IP address
  • Port number
  • Keyspace
  • Username and password
  • SSL certificate (if required by the database server)

For Credentials and Certificates, you can use secrets if a vault is configured for the platform and the service supports vaults. For information, see Using secrets from vaults in connections.

Choose the method for creating a connection based on where you are in the platform

In a project
Click Assets > New asset > Data access tools > Connection. See Adding a connection to a project.
In a catalog
Click Add to catalog > Connection. See Adding a connection asset to a catalog.
In a deployment space
Click Add to space > Connection. See Adding connections to a deployment space.
In the Platform assets catalog
Click New connection. See Adding platform connections.

Next step: Add data assets from the connection

Where you can use this connection

You can use Apache Cassandra connections in the following workspaces and tools:

Projects

  • Data quality rules (Watson Knowledge Catalog)
  • Data Refinery (Watson Studio or Watson Knowledge Catalog)
  • DataStage (DataStage service). See Connecting to a data source in DataStage. The Apache Cassandra (optimized) connection for DataStage gives you increased performance and more features such as before and after SQL statements and reject links. However, you cannot use the "(optimized)" connection outside of the DataStage service.
  • Metadata enrichment (Watson Knowledge Catalog)
  • Metadata import (Watson Knowledge Catalog)
  • SPSS Modeler (SPSS Modeler service)

Catalogs

  • Platform assets catalog
  • Other catalogs (Watson Knowledge Catalog)
