      • getMetaData

        public java.util.List<java.lang.String> getMetaData()
        Specified by:
        getMetaData in interface BasicDao

      • setTimestampRadioX

        public static void setTimestampRadioX​(java.lang.String timestampPrecision)

      • querySeries

        public java.util.List<TimeValues> querySeries​(java.lang.String s,
                                              org.apache.iotdb.tsfile.utils.Pair<java.time.ZonedDateTime,​java.time.ZonedDateTime> timeRange)
        Note: If the query fails this could be due to AGGREGATION like AVG on boolean field. Thus, we then do a retry with FIRST aggregation. This should be solved better in the long run.
