es中max_coordinating_and_primary_bytes大于max_coordinating_and_primary_bytes,1介绍主要介绍索引请求的基础API操作,使用postman进行请求,接口请求的前缀地址统一为elasticsearch部署IP地址+端口号(例如http://192.168.51.4:9200。统一请求地址:POST/search_demo/_d

max_coordinating_and_primary_bytes=2684354560:允许协调节点和主分片处理的最大数据量(字节),即线程池的配置限制。 可能的原因: Elasticsearch集群的负载过高,节点资源(如CPU、内存、磁盘I/O)已经接近或达到饱和。 线程池配置不合理,例如线程池大小过小,或者队列长度设置不当,导致无法处理更多的请求。 集群中存在大...
master eligible:备选主节点。主节点用于处理索引库创建,删除等操作(主节点会自动从备选主节点选取) data:数据结点。存储数据、搜索、聚合还有数据的CRUD等操作都是由它处理的 ingest:在数据被存储前,该结点负责对数据进行过滤处理 coordinating:用于路由,来分配每次请求给哪个结点处理,合并多个结点的处理结果 默认情况...

number_of_primary_shards (索引创建时指定的分片总数)得到的余数就是对应的分片。 当一个查询请求到达仅协调节点(coordinatingonlynode)后,仅协调节点会根据路由公式计算出目标分片,然后再将请求转发到目标分片的主分片节点上。 上面公式也解释了为什么我们要在创建索引的时候就确定好主分片的数量,并且不允许改变索引分...

Coordinating Node 处理请求的节点即为coordinating节点,该节点为所有节点的默认角色,不能取消 路由请求到正确的节点处理,比如创建索引的请求到master节点 Data Node 存储数据的节点即为data节点,默认节点都是data类型,相关配置如下: node.data:true 副本与分片 ...
