Is a Set() call synchronous or asynchronous?

[waltforme]

For example, in the sample code in project's README.md, we have

err := rdb.Set(ctx, "key", "value", 0).Err()
if err != nil {
        panic(err)
}

Looks like Set is synchronous because err must be assigned with a value for the next line of code to run.

Is there an asynchronous way to Set? I'm asking because I am working with a use case where

1. I'll be frequently setting a value;
2. my redis server is on cloud, where there is a considerable delay which may conflict with the high frequency.

All go-redis API is synchronous. You can use channels/goroutines if you need async execution.

I see. Thanks for the reply!
