             Summary: Allow Sub-Devices in IoTDB Server
                 Key: IOTDB-750
                 URL: https://issues.apache.org/jira/browse/IOTDB-750
             Project: Apache IoTDB
          Issue Type: New Feature
          Components: Core/Engine
            Reporter: Julian Feinauer


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.s1 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]
