GitHub user JackieTien97 added a comment to the discussion: Support IoTDB as Time Series Storage
Actually, we're developping on relational model, but it may need several months to be finished. For current tree model of IoTDB, I suggest that you put all your tag dimensions' value into the path, like `root.streampipes.flowrate. flowrate02`. If you have more than one dimension, you can also keep adding that into path, like `root.streampipes.flowrate.West.flowrate02`. Then, if you want to group the data for all dimensions, you can use `align by device` clause (https://iotdb.apache.org/UserGuide/latest/User-Manual/Query-Data.html#align-by-clause-1), like `select avg(temperature) from root.streampipes.flowrate.**`. The only question for this `align by device` way is that it can only group data by all dimensions, if you only need one or some dimensions, you may need to do the aggregation in your client.
