Developed multi-cluster proxy routing support for the CDC replicate client in the milvus-io/milvus repository, focusing on enhancing connectivity in distributed environments. The work involved implementing gRPC authority configuration within the client, enabling seamless routing through proxies when clusters are deployed across different regions or behind network boundaries. By addressing connectivity constraints in proxy-heavy setups, this feature aligned with the broader multi-cluster strategy and reduced operational friction for users. The solution was engineered using Go and leveraged expertise in client-server architecture and testing, ensuring robust integration with existing systems and improving the reliability of cross-cluster communication in complex deployments.
