Hi Xiangdong, thanks for the hint. We should definetly try to keep it similar, yes. I already pushed a minimal working example based on a tsfile [1].
And I would be happy to cooperate with Tianan and Wangminhao (we already had some mail exchanges).

I think, we can consider how the SparkSQL-IoTDB adapter is designed, which is mainly developed by Jialin Qiao and Lei Rui. In summary, a Storage Group is a table, and there are two types of column mappings: 1. the columns are: (timestamp, device_id, measurement1, measurement2...) 2. the columns are: (timestamp, device_1_measurement_1, device_1_measurement_2, ..., device_2_measurement_1, device_2_measurement_2, ...) Tianan Li and Wangminhao Gou are also learning Calcite, maybe they can work with you.
