提高MongoDB搜索性能

MongoDB Search runs a new process, called mongot, alongside the mongod process on each host in your cluster. mongot maintains all MongoDB Search indexes on collections in your databases. The amount of CPU, memory, and disk resources mongot consumes depends on several factors, including our index configuration and the complexity of your queries. MongoDB Search alerts measure the amount of CPU and memory used by MongoDB Search processes.

以下页面包含在配置MongoDB搜索索引和定义MongoDB搜索查询以提高性能时可以应用的建议:

  • MongoDB Search 索引性能

  • AMongoDB Search 查询性能

升级到 NVMe 存储

升级集群以使用 NVMe 会触发该集群上的初始同步。在 mongodmongot 完成初始同步之前, MongoDB Search 不可用。

每当需进行初始同步时,基于文件副本的初始同步将始终用于同步 NVME 集群的所有节点。
