Hi, >First, I want to know why the IoTDB chose to use Tsfile’s data file incremental upload over point-by-point write during IoTDB’s cloud synchronization, I understand this for two reasons: 1. The Tsfile file transfer reduces the amount of data transferred because of file consolidation and data compression; 2. Files sent to the cloud are organized between internal data and files, reducing duplication of work in the cloud. I don’t know if this is right？
You are right :) > Second, based on the current data file uploads, would it be okay, or would it have to wait a while, to synchronize all the Edge database data (the latest unwrapped data) in the cloud? It can only synchronize data over a period of time, not the latest data. Yes, the TsFile-sync has some delay. To synchronize the latest data, we plan to add a new synchronization based on log, which has low latency but high overhead.
