Apache Cassandra connection

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)

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 Refinery (Watson Studio or IBM Knowledge Catalog)
  • DataStage (DataStage service). See Connecting to a data source in DataStage. The Apache Cassandra (optimized) connection gives you increased performance and more features such as before and after SQL statements and reject links. However, you cannot use the Apache Cassandra (optimized) connection outside of the DataStage service.
  • Decision Optimization (Watson Studio and Watson Machine Learning)
  • Metadata enrichment (IBM Knowledge Catalog)
  • Metadata import (IBM Knowledge Catalog)
  • Notebooks (Watson Studio). Click Read data on the Code snippets pane to get the connection credentials and load the data into a data structure. See Load data from data source connections.
  • SPSS Modeler (Watson Studio)

Catalogs

  • Platform assets catalog

  • Other catalogs (IBM Knowledge Catalog)
