在MongoDB中使用批量插入与常规插入相比的性能增益 [英] Performance gain by using bulk inserts vs regular inserts in MongoDB

问题描述

在MongoDB和pymongo中使用批量插入与常规插入的性能增益是什么。批量插入只是常规插入的包装器。

What is the performance gain by using bulk inserts vs regular inserts in MongoDB and pymongo specifically. Are bulk inserts just a wrapper for regular inserts?

推荐答案

批量插入不是普通插入的包装器。批量插入操作包含作为一个整体发送的许多文档。它节省了尽可能多的数据库往返。它性能更高，因为您不必通过网络单独发送每个文档。

Bulk inserts are no wrappers for regular inserts. A bulk insert operation contains many documents sent as a whole. It saves as many database round trips. It is much more performant since you don't have to send each document over the network separately.
