---------------------------------
Summary: 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
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.
