[Clarification] Better to open a persistent client or always to use resource

[Marcus-Rosti]

In a long running server, say a web client, is it better to call use and then pass my client into any dependencies, or is the intended use is that we generate a new client each time via mkRedisClient.use() each time I need it

Definitely create one instance at the beginning of the application and pass it around.
