[jira] [Created] (IOTDB-2405) Support '?' in path pattern

Tian Jiang created IOTDB-2405:
---------------------------------

             Summary: Support '?' in path pattern
                 Key: IOTDB-2405
                 URL: https://issues.apache.org/jira/browse/IOTDB-2405
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: Core/Query
            Reporter: Tian Jiang


The current path pattern lacks an optional-match mark, namely '?'. If I want to find paths that start with "root.sg1" and end with "s1", I will have to execute two queries, "SHOW TIMESERIES root.sg1.**.s1" and "SHOW TIMESERIES root.sg1.s1" since ‘**’ requires at least one level to be matched so "root.sg1.**.s1" does not match "root.sg1.s1".
