BlazingMQ is an open source distributed message queueing framework, which focuses on efficiency, reliability, and a rich feature set for modern-day workflows.
At its core, BlazingMQ provides durable, fault-tolerant, highly performant, and highly available queues, along with features like various message routing strategies (e.g., work queues, priority, fan-out, broadcast, etc.), compression, strong consistency, poison pill detection, etc.
Message queues generally provide a loosely-coupled, asynchronous communication channel ("queue") between application services (producers and consumers) that send messages to one another. You can think about it like a mailbox for communication between application programs, where 'producer' drops a message in a mailbox and 'consumer' picks it up at its own leisure. Messages placed into the queue are stored until the recipient retrieves and processes them. In other words, producer and consumer applications can temporally and spatially isolate themselves from each other by using a message queue to faciliate communication.
BlazingMQ's back-end (message brokers) has been implemented in C++, and client libraries are available in C++, Java, and Python (the Python SDK will be published shortly as open source too!).
BlazingMQ is an actively developed project and has been battle-tested in production at Bloomberg for 8+ years.
