IBM Cloud Databases for DataStax connection

IBM Cloud Databases for DataStax connection

To access your data in IBM Cloud Databases for DataStax, create a connection asset for it.

Note: The IBM Cloud Databases for DataStax connector is discontinued.

IBM Cloud Databases for DataStax is a scale-out NoSQL database in IBM Cloud that is built on Apache Cassandra. It’s designed to power real-time applications with high availability and massive scalability.

Create a connection to IBM Cloud Databases for DataStax

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

  • Host name
  • Port number
  • Username and password
  • Keyspace
  • SSL certificate (if required by the database server)

Recommended values to insert into "SSL certificate", "Key certificate" and "Private key" fields can be found in secure-connect-bundle.zip. It can be downloaded from the Databases for DataStax instance (tab Overview). After downloading secure connect bundle, unzip it, and you'll find the following:

  • SSL certificate property: contents of ca.crt
  • Private key property: contents of key

In order to paste contents of key into Private key property, it has to be parsed to one-line. It can be done for example by executing following in the console: tr -d '\n' < key. The output from this command can be put into Private key property.

  • Key certificate property: contents of cert

For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.

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