----------------------------------
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.
