[GitHub] [iotdb] SzyWilliam opened a new pull request, #7070: [IOTDB-4027] Guarantee atomicity for latest snapshot

SzyWilliam opened a new pull request, #7070:
URL: https://github.com/apache/iotdb/pull/7070

   Currently, when fetching latest snapshot, RatisConsensus will visit snapshot directory by order and pick the largest term_index directory as the latest snapshot. However, this snapshot might be incomplete if state machine crashed during the middle of snapshotting. 
   Thus, we have to decide whether a snapshot dir contains a complete snapshot by testing the existence of meta file (which is added to the snapshot dir last).
