Fivetran Cloud Function Connectors` are a powerful solution for large international enterprises to streamline data integration, reduce costs and boost productivity by leveraging `custom code orchestrated and maintained by Fivetran`, utilizing serverless platforms like AWS Lambda or Azure Functions. They can be used when there isn't a native Fivetran connector for your data source, providing more flexibility and faster implementation compared to custom connectors. These connectors are valuable for supporting sources that Fivetran does not natively support, as well as use cases such as enhancing existing connectors with additional data, in-flight transformations of data, complex pipelines, external orchestration, filtering to extract only a subset of data from a given source, and optimizing data pipelines through source-side filtering. This solution helps reduce costs and boost productivity by streamlining data integration and providing the necessary tools for data science, sharing and monetization projects throughout the Modern Data Stack environment.
