Hi, I'm Xiaojian Sun 👋

About me

My main focus is data infrastructure — streaming, lakehouse, and query systems — through contributions to open-source data projects and connectors of my own. Alongside that, I work on AI agents and the harnesses that run them.

🚧 Currently building — Pangrova: a high-performance distributed SQL query engine for lakehouse architecture, built on Apache Calcite, Apache Arrow, and Velox.

Areas I focus on

  • Streaming & messaging — Apache Kafka · Apache RocketMQ · Apache Fluss
  • Lakehouse & table formats — Apache Paimon · Apache Iceberg
  • Data integration & CDC — Kafka Connect · Apache SeaTunnel
  • Catalogs & metadata — Apache Gravitino
  • Query & analytics — Distributed query engines · Apache Calcite · Apache Arrow · Velox · Trino · Apache Doris
  • AI agents — Agents and agent harnesses

Open-source contributions

Merged contributions to Apache Gravitino · Apache SeaTunnel · Apache Paimon · Apache Fluss · Apache RocketMQ
