Stages of Index Build in MongoDB
Indexes in MongoDB play a crucial role in improving the query performance and increasing the overall database efficiency. Without indexes, MongoDB will perform a collection scan, i.e., it will read all the documents to find if they match the condition specified in the query and cause low response time. Indexes help in navigating directly to […]
索引在MongoDB中起关键作用，提高查询性能和数据库效率。索引帮助导航到相关文档，避免集合扫描，适用于文档较多的集合，提高查询性能和用户体验。索引构建经历多个阶段，包括初始化、IX锁、集合扫描、处理临时写入表、处理约束违规表、设置索引为可用。构建索引时，MongoDB获取独占锁，停止对集合的读写操作。
