Redis connection pools + Node.js

Are Redis connection pools necessary with Node.js asynchronous I/O?

Most of the Redis libraries I see allow you to create client connections but there aren't many connection pool modules so I assume it's not as important.

The one thing that confuses me is that Redis has a default of 16 different/segmented databases in one Redis instance.

So if you create a connection pool, which database of the 16 are you connected to? Can you connect to all 16 at once with the same connection pool?

Is there a Node.js Redis library that creates a connection pool with 1 client per database, depending on how many databases you are using?

You've asked too many questions in one post.

Duplicate of Node.js Redis Connection Pooling

By default you're always connected to database 0. Databases in redis are numbered if you're thinking why 0. They cannot be renamed to a string.

Can you connect to all 16 at once with the same connection pool?

Connection pools are not necessary
