- What is the difference between message queue and message broker?
In order to provide reliable message storage and guaranteed delivery, message brokers often rely on a substructure or component called a message queue that stores and orders the messages until the consuming applications can process them In a message queue, messages are stored in the exact order in which they were transmitted and remain in the
- What is Microsoft Message Queuing (MSMQ)? How does it work?
A Transactional Queue can also participate in a distributed transaction, and a rollback can trigger the disposal of messages This means that a message is guaranteed to be delivered with at-most-once semantics or guaranteed delivery if not rolled back The message won't be delivered if: Host A posts the message but Host B is not connected
- difference between message queue and shared memory?
A message queue is a one-way pipe: one process writes to the queue, and another reads the data in the order it was written until an end-of-data condition occurs When the queue is created, the message size (bytes per message, usually fairly small) and queue length (maximum number of pending messages) are set
- message queue - Performance comparison between ZeroMQ, RabbitMQ and . . .
I need a high performance message bus for my application so I am evaluating performance of ZeroMQ, RabbitMQ and Apache Qpid To measure the performance, I am running a test program that publishes say 10,000 messages using one of the message queue implementations and running another process in the same machine to consume these 10,000 messages
- how Message Queue System Works? - Stack Overflow
The message queue layer uses lower level synchronization schemes to insure that no two writers to the queue can write at the same time It insures that all writes to the queue are atomic It also insures that a reader of the queue cannot read a partially written message from the queue Most message queue APIs also offer support for reading

- Recommendations for C C++ remote message queues
I think a message queue model (fire and forget) makes the most sense and should simplify the logic of each program It is probably sufficient to merely note that the message was added to the remote queue successfully What I am looking for are recommendations for how to implement this message queue in C or C++
