Question

Quick clarification please

I know BlockingQueues are threadsafe.

Does that mean that I can pass a single reference to a blocking queue to all producers who can drop Events in willy-nilly to be consumed by a single consumer, and nothing gets disrupted?

Otherwise having to produce up to 20 BlockingQueues that may or may not have regular updates and reading them with any efficiency seems an insurmountable task.

In a word, yes. This is safe. To quote the documentation:

BlockingQueue implementations are thread-safe. All queuing methods achieve their effects atomically using internal locks or other forms of concurrency control.
