Classes summary
| Claim |
A worker claims or checks out a message to perform a task. Doing so prevents
other workers from attempting to process the same messages. |
| Message |
A message is a task, a notification, or any meaningful data that gets posted to
the queue. A message exists until it is deleted by a recipient or automatically
by the system based on a TTL (time-to-live) value. |
| Queue |
A queue holds messages. Ideally, a queue is created per work type. For example,
if you want to compress files, you would create a queue dedicated to this job.
Any application that reads from this queue would only compress files. |
