Description

Add an efficient interface for aggregation query that can save SQL parsing cost.

• Support specified query time range: The specified query time range is a left-closed right-open interval, including the start time but not the end time.
• Support GROUP BY TIME.

SessionDataSet executeAggregationQuery(List<String> paths, List<Aggregation> aggregations);

SessionDataSet executeAggregationQuery(
    List<String> paths, List<Aggregation> aggregations, long startTime, long endTime);

SessionDataSet executeAggregationQuery(
  List<String> paths,  
  List<Aggregation> aggregations,
  long startTime,
  long endTime,
  long interval);

SessionDataSet executeAggregationQuery(
  List<String> paths,
  List<Aggregation> aggregations,
  long startTime,
  long endTime,
