The Project Management Committee (PMC) for Apache IoTDB is delighted to announce that [PMC Member Name] has joined the PMC! Rongzhao’s most notable contribution is the design and implementation of the ConfigNode—one of the cornerstone of our first officially distributed release (version 1.0). Entrusted with cluster management and load-balancing responsibilities, he not only delivered a resilient foundation but also introduced three novel, time-series-specific algorithms: the data partitioning table, the replica placement and the leader election strategies. These innovations culminated in his research paper, “Migration-Free Elastic Storage of Time Series in Apache IoTDB,” which has been accepted by VLDB 2025. Building on this momentum, Rongzhao spearheaded the development of the AINode for version 2.0, establishing IoTDB’s native machine-learning kernel. By assimilating cutting-edge research on time-series foundation models, he seamlessly integrated the Timer family into the codebase, significantly expanding IoTDB’s analytical capabilities. In total, Rongzhao has committed nearly 300 changes to the repository over the past five years. Beyond code, he continually enriches our community with academic insights while maintaining the engineering pragmatism required to realize ambitious ideas.
The PMC - Project Management Committee - manages and guides the direction of the project, and is responsible for inviting new committers and PMC members to steward the longevity of the project.
