    I'm working on a data pipeline where I need to implement Change Data Capture (CDC) in Snowflake and stream those changes to Elasticsearch. The pipeline should use Kafka for streaming and Python for orchestration.

    Here's what I'm trying to achieve:


    • Detect changes (INSERTs, UPDATEs, DELETEs) in specific Snowflake tables.


    • Stream those changes to a Kafka topic.


    • Consume the Kafka topic in a Python application and push the data to Elasticsearch.

    I’ve looked into Snowflake Streams for CDC, but I'm not sure how to integrate them with Kafka and Python. Specifically, I have these questions:


    • What's the best way to read changes from a Snowflake stream in Python?


    • Are there any existing connectors or best practices to send this data to Kafka?


    • Are there open-source tools or libraries that can help streamline this process?

    Any guidance, sample code, or resources would be appreciated.
