I have a question about the combination use of TTL and data synchronization between multiple Apache IoTDB database. The two databases require different data storage durations. One IoTDB database is for handling expired data using TTL. The other IoTDB database stores all historical data and synchronize the data source from the previous IoTDB database. I wonder whether expired data set by TTL in the previous IoTDB will be synchronized and delete again in the later IoTDB. If it still will be synchronize and delete, are there any other better way?
