Using the message group ID with Amazon SQS FIFO Queues (original) (raw)

DocumentationAmazon Simple Queue ServiceDeveloper Guide

In FIFO (First-In-First-Out) queues, MessageGroupId is an attribute that organizes messages into distinct groups. Messages within the same message group are always processed one at a time, in strict order, ensuring that no two messages from the same group are processed simultaneously. In standard queues, using MessageGroupId enables fair queues. If strict ordering is required, use a FIFO queue.
