Requirements

To extract metadata using the Cassandra connector, ensure the user in the connection has the following permissions:

  • Read Permissions: The ability to query tables and perform data extraction.
  • Schema Operations: Access to list and describe keyspaces and tables.

Metadata Ingestion

Connection Details

  • Username: Username to connect to Cassandra. This user must have the necessary permissions to perform metadata extraction and table queries.
  • Host Port: When using the cassandra connecion schema, the hostPort parameter specifies the host and port of the Cassandra. This should be specified as a string in the format hostname:port. E.g., localhost:9042.- databaseName: Optional name to give to the database in OpenMetadata. If left blank, we will use default as the database name.

Auth Type: Following authentication types are supported:

  1. Basic Authentication: We'll use the user credentials to connect to Cassandra
  • password: Password of the user.
  1. DataStax Astra DB Configuration: Configuration for connecting to DataStax Astra DB in the cloud.
  • connectTimeout: Timeout in seconds for establishing new connections to Cassandra.
  • requestTimeout: Timeout in seconds for individual Cassandra requests.
