-----------------------------------

             Summary: Using `show timeseries` to query the schema in import-csv
                 Key: IOTDB-5028
                 URL: https://issues.apache.org/jira/browse/IOTDB-5028
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: Client/CLI
            Reporter: Xuan Ronaldo
            Assignee: Xuan Ronaldo
             Fix For: master branch


The import-csv tool is using `select * from ... limit 1` to query the schema. It will cost a lot of performance. Therefore, we need to use `show timeseries` to query the schema.
