> URL: https://issues.apache.org/jira/browse/IOTDB-750
> Project: Apache IoTDB
> Issue Type: New Feature
> Components: Core/Engine
> Reporter: Julian Feinauer
> Assignee: Julian Feinauer
> Priority: Major
> Labels: pull-request-available

>
> Currently, a Node is considered a Device if it has a measurement. Then it is
> not possible that this devices has a "subpath" which again is a device but
> only measurements.
>
> This should be changed so that a Device can also have "subdevices".
>
> Example:
> {code:java}
> CREATE TIMESERIES root.sg1.d1.s1 with datatype=INT32,encoding=RLE;
> CREATE TIMESERIES root.sg1.d1.d2.s1 with datatype=INT32,encoding=RLE;
> CREATE TIMESERIES root.sg1.d1.d2.s2 with datatype=INT32,encoding=RLE;
> {code}
> Currently the first command succeeds but the second and third fail.
> But they should also be possible.
>
> Note: Example above is from [~jixuan1989]
