Is Producer thread-safe?

[wkuranowski]

Hi.

I would like to create a single Producer and share it between workers (goroutines). Is it safe and efficient? Is it better to create many clients/producers?

Regards.

Yes, it should be both safe and efficient.

So does this mean that if a sendMessage in one goroutine is blocking for a given producer, it wont affect that same producer's calls to sendMessage in other goroutines?

Thanks,

Dhruv

Depends on what you mean by "affect" - both messages should absolutely be safely delivered, but I'm not sure the performance impact. There are definitely some synchronization points between the goroutines, but I don't think they wrap any of the major work (specifically the network round-trip) so it should be relatively performant. It won't be as fast as fully-asynchronous producing (with QueueMessage) of course. The best way to find out for sure would be to try it and see :)
