Custom Connectors

Connector Framework

The connector framework is a Python SDK that lets you build custom connectors for any data source. Implement the Connector interface with three methods: discover_schema, read_data, and validate_connection. Your connector automatically gets schema inference and validation.

Interface Methods

discover_schema returns the data structure the connector provides. read_data executes the actual data fetch with configurable batching and pagination. validate_connection tests connectivity and returns any configuration errors.

Packaging

Custom connectors are packaged as Python wheels and registered with the Altius connector registry. Once registered, they appear in the connector browser alongside built-in connectors and can be used in any pipeline.
