[zeromq-dev] Can drop the first message when high water mark has been reached with socket ROUTER ?

[Pieter Hintjens]

No, you cannot drop older messages in pipe buffers to make space for
newer ones. This is technically impossible without slowing things down
considerably.

A good approach is to use credit-based flow control to avoid ever
sending more data than the receiver expects and asks for. There's a
discussion of this in the Guide and examples.
