在Node Stats Api中，滚动参数指示什么? [英] In Node Stats Api what does scroll parameters indicate?

问题描述

在节点统计API (_nodes/stats/indices)索引的响应具有以下搜索主体"search":{"open_contexts":15，"query_total":52511，"query_time_in_millis":1588864，"query_current":0，"fetch_total:46521，" fetch_time_in_millis:326，" fetch_current:0，" scroll_total:1110，" scroll_time_in_millis:3928255092，" scroll_current:530，" suggest_total:0，" suggest_time_in_millis:0，"0}，滚动参数(scroll_total，scroll_time_in_millis，scroll_current)在此处表示什么?

In the Node stats API (_nodes/stats/indices) the response for an index has following search body, "search": { "open_contexts": 15, "query_total": 52511, "query_time_in_millis": 1588864, "query_current": 0, "fetch_total": 46521, "fetch_time_in_millis": 326210, "fetch_current": 0, "scroll_total": 1110, "scroll_time_in_millis": 3928255092, "scroll_current": 530, "suggest_total": 0, "suggest_time_in_millis": 0, "suggest_current": 0}, what does scroll parameters(scroll_total, scroll_time_in_millis, scroll_current) indicate here?

推荐答案

• scroll_current 指示当前打开的滚动上下文的数量
• scroll_total 指示自节点上次重启以来已完成的滚动上下文的数量
• scroll_time_in_millis 指示自上次重启节点以来滚动上下文一直保持打开状态的时间
• scroll_current indicates the number of scroll contexts currently open
• scroll_total indicates the number of scroll contexts that have been completed since the node last restarted
• scroll_time_in_millis indicates the time that scroll contexts have been held open since the node last restarted
