Dear Yuan Tian Thank you for your reply. Your response was very helpful. But I have an additional question here.
Since the original data is stored in MongoDB, the issue arises because it is not time series data. After discussing with my colleagues, we've decided that adding an offset to modify the original data is not an option. And I found information about using tags in IoTDB. So, I have a question regarding the use of tags. As far as I understand, when using tags in IoTDB, it is done as follows, based on what I observed on the website. root.db.tag1.tag2.device.sensor_value Here comes my question. If I want to attach a unique tag to each tuple to avoid duplicates, is it possible to use MongoDB's objectId as a tag and create a time series like the following in IoTDB? create timeseries root.db.objectId.device.longitude DOUBLE, encoding=plain insert into root.db.objectId.device(timestamp, longitude) values(1, 33.33) Or is there *any other way* to use the objectId as a tag in IoTDB? Secondly, if I were to use such a way, how could I select information such as the longitude for each tuple? select longitude from root.db.** I couldn't select the data using the method mentioned above. If objectId is inserted into a timeseries in the IoTDB tree structure, could you please provide guidance on how to access the values of each tuple? Thank you for your time and assistance on this matter. Best regards, ----------------------------------- Cheongu Kim [email protected]
