**Requirement source:** In the situation that there exist a large number of timeseries, it would take a long time to restart IoTDB by reading mlog.txt and executing the commands line by line. For example, it takes about 2 minutes to restart with 20M timeseries. **Basic ideas:** Every time mlog.txt reaches a certain number of lines, Generate a snapshot, which includes the serialization of MTree. When a new snapshot is generated, the old one is deleted. Snapshot file and mlog.txt are in the same directory. **User configuration:** Users could configure the threshold number of the mlog lines `mtree_snapshot_interval`. By default, a snapshot is generated for every 100k lines. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
