使用mongoose驱动程序在mongodb中进行并发请求的nodejs中，一个连接是否足够？

Question

Is it possible to have one single connection poolsize { poolSize: 1 } for multiple and concurrent webservice hit in mongodb

Will it reuse the connection or will throw any exception

I'm Using mongoose driver in nodejs and mongoDB as database.

Answer 1

It will reuse the connection, but it will slow down your database calls, as there is a limit of only one active connection to the database. This will cause issues when you scale up to higher loads.
