								In this section, we provide guides and references to use the Cassandra connector.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								Configure and schedule Cassandra metadata workflows from the OpenMetadata UI:

								 | 
							
								## 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.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								### Python Requirements
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% partial file="/v1.7/connectors/python-requirements.md" /%}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								To run the Cassandra ingestion, you will need to install:
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								```bash
							 | 
						||
| 
								 | 
							
								pip3 install "openmetadata-ingestion[cassandra]"
							 | 
						||
| 
								 | 
							
								```
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								## Metadata Ingestion
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								All connectors are defined as JSON Schemas.
							 | 
						||
| 
								 | 
							
								[Here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/entity/services/connections/database/cassandraConnection.json)
							 | 
						||
| 
								 | 
							
								you can find the structure to create a connection to Cassandra.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								In order to create and run a Metadata Ingestion workflow, we will follow
							 | 
						||
| 
								 | 
							
								the steps to create a YAML configuration able to connect to the source,
							 | 
						||
| 
								 | 
							
								process the Entities if needed, and reach the OpenMetadata server.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								The workflow is modeled around the following
							 | 
						||
| 
								 | 
							
								[JSON Schema](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/workflow.json)
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								### 1. Define the YAML Config
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								This is a sample config for Cassandra:
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% codePreview %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% codeInfoContainer %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								#### Source Configuration - Service Connection
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% codeInfo srNumber=1 %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								**username**: Username to connect to Cassandra. This user must have the necessary permissions to perform metadata extraction and table queries.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% /codeInfo %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% codeInfo srNumber=3 %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								**hostPort**: 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`.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% /codeInfo %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% codeInfo srNumber=4 %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								**databaseName**: Optional name to give to the database in OpenMetadata. If left blank, we will use default as the database name.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% /codeInfo %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								{% codeInfo srNumber=5 %}
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								**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.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								2. **DataStax Astra DB Configuration**: 
							 | 
						||
| 
								 | 
							
								Configuration for connecting to DataStax Astra DB in the cloud.
							 | 
						||
| 
								 | 
							
								  - **secureConnectBundle**: File path to the Secure Connect Bundle (.zip) used for a secure connection to DataStax Astra DB.
							 | 
						||
| 
								 | 
							
								  - **token**: The Astra DB application token used for authentication.
							 | 
						||
| 
								 | 
							
								  - **connectTimeout**: Timeout in seconds for establishing new connections to Cassandra.
							 | 
						||
| 
								 | 
							
								  - **requestTimeout**: Timeout in seconds for individual Cassandra requests.
							 | 
						||
| 
								 |

						||
| 
								 |
