为了保证 Elasticsearch 的可靠性,需要确保数据变化被持久化到磁盘。 在动态更新索引,我们说一次完整的提交会将段刷到磁盘,并写入一个包含所有段列表的提交点。Elasticsearch 在启动或重新打开一个索引的过程中使用这个提交点来判断哪些段隶属于当前分片。 即使通过每秒刷新(refresh)实现了近实时搜索,我们仍然需要经常进行...
refresh=wait_for 这个参数表示,刷新不会立刻进行,而是等待一段时间才刷新 ( index.refresh_interval),默认时间是 1 秒 查询过程 客户端将请求发送到任一节点node,该node也就成为了协调节点,协调节点会进行分词等操作,将处理后的结果分发到所有分片,然后分片将符合要求的数据id排序之后返回给路由节点,路由节点重新...

1)调整refresh interval 根据你的系统要求调整 refresh_interval(默认 1 秒)。在很多的情况下,我们甚至可以把 refresh_interval 设置为 -1,这样可以最大限度地提高导入数据的速度。作为一个规则,当 refresh_interval 值越大,导入速度就会提高的越快。当我们把它设置为 -1 时,refresh 就被终止。 我们可以通过如下...
