Are there any non-blocking node.js db drivers for redis, mongo or mysql?

I know there are blocking drivers for these and have used them but am looking for non-blocking node d开发者_开发百科rivers. thanks.

node-mongodb-native is an excellent, non-blocking Node driver for MongoDB. It also contains optional C-based BSON extensions for performance.

Non-blocking MySql drivers:

native JS, non-blocking due to event loop

• http://github.com/felixge/node-mysql
• https://github.com/sidorares/nodejs-mysql-native
• https://github.com/sidorares/node-mysql2

libmysqlclient bindings, non-blocking with node thread pool

• http://github.com/Sannis/node-mysql-libmysqlclient

libmariasql bindings:

For portability, a pure JavaScript reply parser is used by default. Pieter Noordhuis has provided a binding to the official hiredis C library, which is non-blocking and fast. To use hiredis, do:

npm install hiredis redis
