mongodb聚合怎么查看查询性能？

Question

用find可以使用explain('executionStats')查看查询分析，但是aggregate用没有explain查询分析了，根本看不出它有没有用索引，是否在内存排序这些问题啊...

Answer 1

You might as well read more official documents.

https://docs.mongodb.com/manu...

db.collection.aggregate(pipeline, options)

The options document can contain the following fields and values:explain,allowDiskUse,etc.
