Houliang Qi commented on IOTDB-910:
-----------------------------------
For example
# query the timeseries created in 20200923,
## show timeseries where create_time = 20200923
# query the timeseries created last week
## show timeseries where create_time between in [now-7days, 7days]
# query the new devices added after 20200923
## show device where create_time >= 20200923
> Support time range interval query of metadata(timeseries,devices) and so on

> Maybe we can treate the metadata(timeseries) as special data like the
> timeseries's values. and support metadata query like data query.
> One way to do this is to add the metadata to one metadata_table, like the
> information_schema.tables of mysql.
