FIFO Queues

• FIFO (First-In-First-Out) queues are designed to enhance messaging between applications when the order of operations and events is critical, or where duplicates can't be tolerated.

• FIFO queues also provide exactly-once processing but have a limited number of transactions per second (TPS).

Examples

• Ensure that user-entered commands are executed in the right order.

• Display the correct product price by sending price modifications in the right order.

• Prevent a student from enrolling in a course before registering for an account.
