# Namespace OpenCloud\Queues\Resource

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.
