PROFILE

Zhonchen

Zhonchen contributed to the linkedin/rest.li repository by developing and refining backend features focused on dynamic routing and system reliability. Over three months, he built glob collection URI change tracking in XdsClient, enhancing D2URIMapUpdate to accurately report updated and removed URIs, which reduced stale routing data. He improved shutdown reliability in XdsClientImpl and XdsLoadBalancer, optimizing resource management and preventing unnecessary ZooKeeper node creation. Zhonchen also delivered a pre-check mechanism for INDIS/XDS connections, validating Java version and network health to ensure robust client initialization. His work leveraged Java, gRPC, and build automation, demonstrating depth in distributed systems and backend engineering.

April 2025: Focused on improving dynamic routing reliability in linkedin/rest.li by delivering a feature for glob collection URI changes tracking in XdsClient. The changes ensure D2URIMapUpdate tracks updated and removed URIs when glob collections are enabled, leading to accurate reporting of URI updates/removals and reduced risk of stale routing data. The work aligns with ongoing improvements to XDS-based dynamic configuration and lays groundwork for broader glob collection support across services.
