Xiangdong Huang reassigned IOTDB-349:
-------------------------------------
Assignee: Tianan Li
> [Distributed] Incrementally update snapshot
> -------------------------------------------
>
> Key: IOTDB-349
> URL: https://issues.apache.org/jira/browse/IOTDB-349
> Project: Apache IoTDB
> Issue Type: Improvement
> Reporter: Tian Jiang
> Assignee: Tianan Li
> Priority: Minor
> Labels: distributed
>
> Currently, the snapshot is fully recalculated when takeSnapshot() is called.
> It does not count much since snapshot-taking is relatively rare and the
> snapshot mainly concerns the list of the data files and timeseries schemas,
> not including the data.
> Still, using an incremental strategy would help to reduce meta tree
> traversing and file listing.
