> Key: IOTDB-3908
> URL: https://issues.apache.org/jira/browse/IOTDB-3908
> Project: Apache IoTDB
> Issue Type: New Feature
> Reporter: Jialin Qiao
> Priority: Minor
>
> Sometimes, we need to troubleshoot the start process of an IoTDB instance,
> however, there are too much historical data, which leads to transferring too
> much data.
> Therefore, we could only copy the data/system and data/wal folder into the
> local.
> However, recovering wal need the related .tsfile (empty file) in the right
> place under data/data folder.
> Therefore, we need a tool to reconstruct the data/data folder based on
> data/wal.
