Houliang Qi reassigned IOTDB-1292: ---------------------------------- Assignee: Houliang Qi > Differentiable MTree > -------------------- > > Key: IOTDB-1292 > URL: https://issues.apache.org/jira/browse/IOTDB-1292 > Project: Apache IoTDB > Issue Type: Improvement > Components: Core/Cluster > Reporter: Tian Jiang > Assignee: Houliang Qi > Priority: Major > Labels: metadata, synchronization > > We have the sync tool for incremental data file synchronization, but it is > non-trivial to synchronize metadata incrementally since two MTrees cannot be > compared at a low cost. > So differentiable MTree is necessary to make it possible to compare two > MTrees and find the difference between them. When synchronizing the metadata, > only the difference will be transmitted and thus the bandwidth usage is > reduced. -- This message was sent by Atlassian Jira (v8.3.4#803005)
