# Queues

Queues are named entities within a Virtual Host that hold/buffer messages for delivery to consumer applications.

Different types of Queue have different delivery semantics. The following Queues types are currently supported:

- Standard: a simple First-In-First-Out (FIFO) queue

- Priority: delivery order depends on the priority of each message

- Sorted: delivery order depends on the value of the sorting key property in each message

- Last Value Queue: also known as an LVQ, retains only the last (newest) message received with a given LVQ key value.

Queue configuration details are covered in .
