问题描述
使用 Kibana 的 Dev Tools 工具查询 从第 10001 条到 10010 条数据。
查询语句如下:
GET alarm/_search { "from": 10000, "size": 10 }
查询结果,截图如下:
报错信息如下:
{ "error": { "root_cause": [ { "type": "query_phase_execution_exception", "reason": "Result window is too large, from + size must be less than or equal to: [10000] but was [10010]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting." } ], "type": "search_phase_execution_exception", "reason": "all shards Failed", "phase": "query", "grouped": true, "Failed_shards": [ { "shard": 0, "index": "alarm", "node": "hdLJanxRTbmF52eK6-FFgg", "reason": { "type": "query_phase_execution_exception", "reason": "Result window is too large, from + size must be less than or equal to: [10000] but was [10010]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting." } } ] }, "status": 500 }
原因分析
Elasticsearch 默认查询结果最多展示前 10000 条数据。
解决方案
按照报错信息里的提示,可以看到,通过设置 max_result_window 的值来调整显示数据的大小:
This limit can be set by changing the [index.max_result_window] index level setting.
两种方式可以实现:
【方式一】(修改完配置文件,需要重启集群中的 ES 服务)
修改Elasticsearch 集群中的 配置文件 config/elasticsearch.yml
max_result_window: 200000000
【方式二】(推荐)
具体操作命令,如下(比如,设置可查询 200000000 条数据,其中 alarm 是index名称):
PUT alarm/_settings { "max_result_window" : 200000000 }
命令执行效果,截图如下:
