Java Elasticsearch多条件分组聚合查询

需求
        在项目开发中，需要从elasticsearch中查询日志数据，先统计每一天的日志调用量，然后在每一天的分组聚合基础上，再分组聚合统计成功和失败的日志调用量。

代码

DateHistogramAggregationBuilder aggregationBuilderByTime = AggregationBuilders
        .dateHistogram("dateDownStreamRequestTime")
        .field("downStreamRequestTime")
        .calendarInterval(DateHistogramInterval.DAY)
        .offset("-8h")
        .minDocCount(0)
        .order(BucketOrder.aggregation("_key", true))
        .subAggregation(AggregationBuilders.terms("by_status").field("responseState"));

sourceBuilder.aggregation(aggregationBuilderByTime);
