python elasticsearch date_histogram聚合查询

标签:增加 bool tar trying 报错 iba ons sea utc es版本7.6。 在使用python操作es执行date_histogram后台报错“elasticsearch.exceptions.TransportError:TransportError(503...”,kibana里执行同样的条件,报“Trying to create too many buckets. Must be less than or equal to: [10000]”。 后来发现是"time_zone"和"extended_bounds"出的问题,time_zone我设置的是东8区,而extended_bounds中的starttime和endtime还是UTC,因此endtime要在8小时之后,时间跨度很大,导致buckets数量超出限制。需要对extended_bounds日期也增加8小时。 python elasticsearch date_histogram聚合查询 标签:增加 bool tar trying 报错 iba ons sea utc 原文地址:https://www.cnblogs.com/zd1009/p/12977779.htmles = Elasticsearch([‘127.0.0.1:9200‘], http_auth=(‘elastic‘, ‘elastic‘), timeout=50000)
