In Martin Thompson's talks about Aeron he mentions writing threads doing an increment on an AtomicLong counter to claim a region in a buffer, but the initial 4 bytes for the length field aren't written, but only on completion of the frame, the length is set. This signals to the reader of the buffer that this particular write is complete and provides a happens before relation.
My question is about this length field; who is responsible for zero'ing it out? Once the buffer has been written, the content could be total gibberish and if it isn't zero'd, the reading thread could falsely assume it is written and boom.. -- You received this message because you are subscribed to the Google Groups "mechanical-sympathy" group.
