Message queue
In short and in plain language
A message queue is a waiting line for tasks in a shop.
The tasks are done one by one in the background, such as sending emails.
If the line gets stuck, people often notice it only late.
Definition
A message queue is a waiting line for tasks that a shop handles one after another in the background, not immediately. These include, for example, sending emails, indexing or exports. If the queue stalls, such tasks often go unnoticed for a while.
