    • Get views, procedures, function code
  • JDBC driver is provided by default.

Connection Details

The following connection settings should be added for connecting to a Cassandra database:

  • Database Type: Cassandra
  • Connection Name: Select a Connection name for the Cassandra database. The name that you specify is a reference name to easily identify your Cassandra database connection in OvalEdge.
