    Description

      We need to optimize the following query methods for aligned timeseries

      • AlignByDevice
      • AggregationWithValueFilter
      • AggregationWithoutValueFilter
      • GroupByWithValueFilterDataSet
      • GroupByWithoutValueFilterDataSet
      • GroupByLevel
      • Fill
      • Last(包括last的cache设计)
      • RawQueryWithValueFilter
      • UDF Quer
      • 客户端sql的列顺序与实际查询返回的列顺序的映射关系改动
      • 带值过滤的查询需要设计讨论后再实现
