Node.js Redis Connection Pooling

问题:

When using node_redis Node.js module with Redis, should I just use one connection as Redis is single thread process or shall I create a pool of connections to improve performance?

回答1:

Just use a single connection. Both Node and Redis are effectively single thread. I don't think you'll gain anything by having multiple connections. I asked a similar question before starting to develop with Redis and it seems that one client/one application is pretty effective pattern.

回答2:

There is a use case for pooling multiple connections, actually: blocking commands like BRPOP and SUBSCRIBE.
