报错信息
ES 执行聚合查询时报错，报错信息如下：
{
"root_cause": []
"type": "search_phase_execution_exception",
"reason": "",
"phase": "fetch",
"grouped": true,
"failed_shareds": [],
"caused_by": {
"type": "too_many_buckets_exception",
"reason": "Trying to create too many buckets. Must be less than or equal to: [65535] but was [65536]. This limit can be set by changing the [search.max_buckets] cluster level sitting."
"max_buckets": 65535
}
}
原因定位
因为聚合查询的桶数超过了 ES 集群配置的最大桶数的上限。ES 聚合查询最大桶数的参数文档如下（地址）：
search.max_buckets(Dynamic, integer) Maximum number of aggregation buckets allowed in a single response. Defaults to 65,536.文章来源：https://www.toymoban.com/news/detail-763199.html
Requests that attempt to return more than this limit will return an error.文章来源地址https://www.toymoban.com/news/detail-763199.html
解决方案
- 调整聚合查询方法，使用其他方法实现查询
- 修改 ES 集群配置的最大桶数上限
PUT /_cluster/settings
{
"persistent" : {
"search.max_buckets" : 1000000
}
}
