[GSoC 2026] Flink connector for IoTDB table mode – prospective contributor

[anukalp2804]

Hello,

I’m Anukalp, a CS undergraduate with a strong interest in Java-based backend and data integration systems. I’ve been going through the GSoC idea around building a Flink connector for Apache IoTDB 2.X table mode, and the scope and motivation behind the project are very clear and interesting.

From my understanding, the existing Flink connectors mainly focus on the tree mode, and this project aims to provide first-class support for IoTDB’s table mode through Flink’s DataStream and Table APIs, including schema mapping, read/write support, and fault tolerance.

I’m preparing for GSoC 2026 and plan to start by exploring the existing flink-iotdb-connector, the table-mode SQL features in IoTDB 2.X, and Flink’s connector architecture. I had a couple of questions:

• Are there specific modules or existing connectors you would recommend focusing on first to better understand the current limitations around table mode?
• For the initial implementation, do you see it leaning more toward the Flink Table API, or should both the Table and DataStream APIs be considered from the beginning?

I’d appreciate any guidance on how to prepare effectively and where early exploratory contributions would be most useful.

Thank you for your time.
