WangChao commented on IOTDB-829:
--------------------------------
Hi, I will try to implement this feature.
I will maintain a global modification file for one storage group. When query,
the executor will check the file to filter the series.

> Project: Apache IoTDB
> Issue Type: New Feature
> Components: Core/Engine
> Reporter: Jialin Qiao
> Priority: Major
>
> When deleting N timeseries in a storage group which has M tsfiles. We need to
> record N*M modifications, which is time consuming.
>
> Suppose the sql is : delete timeseries root.sg.* d1
>
> we could write "root.sg.*.d1" in .mods files directly and match series when
> query.
