Airbyte Python CDK and Low-Code CDK

Airbyte Python CDK is a framework for building Airbyte API Source Connectors. It provides a set of classes and helpers that make it easy to build a connector against an HTTP API (REST, GraphQL, etc), or a generic Python source connector.

Building Connectors with the CDK

If you're looking to build a connector, we highly recommend that you first start with the Connector Builder. It should be enough for 90% connectors out there. For more flexible and complex connectors, use the low-code CDK and SourceDeclarativeManifest.

For more information on building connectors, please see the Connector Development guide on docs.airbyte.com.

Python CDK Overview

Airbyte CDK code is within airbyte_cdk directory. Here's a high level overview of what's inside:

airbyte_cdk/connector_builder. Internal wrapper that helps the Connector Builder platform run a declarative manifest (low-code connector). You should not use this code directly. If you need to run a SourceDeclarativeManifest, take a look at source-declarative-manifest connector implementation instead.
airbyte_cdk/cli/source_declarative_manifest. This module defines the source-declarative-manifest (aka "SDM") connector execution logic and associated CLI.
airbyte_cdk/destinations. Basic Destination connector support! If you're building a Destination connector in Python, try that. Some of our vector DB destinations like destination-pinecone are using that code.
airbyte_cdk/models expose airbyte_protocol.models as a part of airbyte_cdk package.
airbyte_cdk/sources/concurrent_source is the Concurrent CDK implementation. It supports reading data from streams concurrently per slice / partition, useful for connectors with high throughput and high number of records.
airbyte_cdk/sources/declarative is the low-code CDK. It works on top of Airbyte Python CDK, but provides a declarative manifest language to define streams, operations, etc. This makes it easier to build connectors without writing Python code.
airbyte_cdk/sources/file_based is the CDK for file-based sources. Examples include S3, Azure, GCS, etc.
