Message ordering

In general, messages produced by a single producer to a single destination will be seen by a consumer to that destination in the same order as they were produced. However there are certain events, such as system failures, that can change the order of messages.

Message reordering can be avoided if the following rules are applied: These rules assure correct ordering of the messages consumed by a single consumer, however they do not guarantee that the consumer will receive all messages produced by the producer. Whether the consumer receives all messages can be affected for a number reasons, including the reliability of the messages and the consumer's selection criteria.
