[jira] [Created] (IOTDB-2011) Update last cache while doing show latest timeseries query

Yuan Tian created IOTDB-2011:
--------------------------------

             Summary: Update last cache while doing show latest timeseries query
                 Key: IOTDB-2011
                 URL: https://issues.apache.org/jira/browse/IOTDB-2011
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: Core/Query
            Reporter: Yuan Tian
            Assignee: Yuan Tian


While doing show latest timeseries query, we will use last update time of that timeseries as the sort order. If the last cache in MNode missed, we will read from disk. And after reading from disk, we should update the last cache for the future querying.
