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