The MessageOptions Structured Data Type is defined under the GeneXusMessagingQueue.SimpleQueue module and allows you to make general settings when using the Queue API.


Depending on the method and the provider, the meaning of the property may vary.

Warning: The recommendation for using any of these properties is to check the documentation of the corresponding provider.

  Azure Storage Queue AWS SQS
MaxNumberOfMessages Receive messages method:
A nonzero integer value that specifies the number of messages to retrieve from the queue, up to a maximum of 32. See this reference.
Receive messages method:
The maximum number of messages to return. Amazon SQS never returns more messages than this value (however, fewer messages might be returned). Valid values: 1 to 10. Default: 1. See this reference.
WaitTimeout ----

Receive method:
In the documentation of SQS is called WaitTimeSeconds
The duration (in seconds) for which the call waits for a message to arrive in the queue before returning. If a message is available, the call returns sooner than WaitTimeSeconds. If no messages are available and the wait time expires, the call returns successfully with an empty list of messages. See this reference.

See also this doc.
