Superficially, stormmq seems to be like Amazon’s SQS, but they have very different message properties.
Amazon SQS and stormmq both support message properties. These are meta data that can be attached to your message (a bit like headers are attached to email) that help an application process a message. A classic example is a message id. However, both systems differ vastly in the range of properties offered, their granularity and understanding by the server.
