[jira] [Created] (IOTDB-526) [Distributed]Support metadata queries

Tian Jiang created IOTDB-526:
--------------------------------

             Summary: [Distributed]Support metadata queries
                 Key: IOTDB-526
                 URL: https://issues.apache.org/jira/browse/IOTDB-526
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Tian Jiang
            Assignee: Tian Jiang
             Fix For: master branch


Metadata queries, like "getNodeList", "getPathNextChildern", "getTimeseriesSchema" are currently unsupported. The point is that the paths being queried may contain wildcards(*) or they may be prefix paths, which makes it a little hard to figure out which data groups to send the query. 

The simplest way may be performing a broadcast and merge the results, which is clearly less efficient. I am hoping you can give a more brilliant idea to resolve this.
