Summary of Changes
Hello @otoolep, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request primarily refines the Change Data Capture (CDC) FIFO queue implementation, enhancing its robustness and integration. It introduces marshaling and unmarshaling of CDC events for persistent storage within the FIFO, and refactors how the service handles leader election, ensuring events are processed and deleted from the queue only when the node is the cluster leader. Additionally, it integrates a new CircleCI job to build and test the project on Windows, specifically for Go code with CGO.
Highlights
- CDC FIFO Event Handling: Events within the CDC FIFO queue are now handled as pointers and are marshaled to bytes for persistence, then unmarshaled back for processing.
- Dynamic Leader-based Event Processing: The CDC service now internally manages its leadership status, dynamically starting to read and process events from the FIFO only when it is the cluster leader, and stopping when it is not.
- Automated FIFO Cleanup: Processed events are now automatically deleted from the FIFO queue up to the reported high watermark, ensuring efficient storage management.
- Windows CI Integration: A new CircleCI job has been added to the CI pipeline to build and test the Go project on Windows, including support for CGO using MinGW.

Code Review
This pull request introduces two main changes: the addition of a CircleCI workflow for building and testing on Windows, and a significant refactoring of the CDC (Change Data Capture) service. The CDC service is updated to use a persistent FIFO queue for events, improving its resilience to leadership changes. The logic for handling leadership transitions is now more robust, with the service managing its own leadership state and starting/stopping event processing from the queue accordingly. The changes are well-implemented and include corresponding test updates. I have one minor suggestion to remove some dead code for better maintainability.

This if/else block is empty and serves no purpose. It appears to be leftover code and should be removed to improve code clarity.
