Indicates whether the message should be settled using the completeMessage()
method on the receiver automatically after it executes the user provided message callback.
Doing so removes the message from the queue/subscription.
This option is ignored if messages are received in the receiveAndDelete receive mode or if
the message is already settled in the user provided message callback.
Default: true.
Optional maxConcurrentCalls
maxConcurrentCalls:undefined | number
property
The maximum number of concurrent calls that the library
can make to the user's message handler. Once this limit has been reached, more messages will
not be received until atleast one of the calls to the user's message handler has completed.
Options used when subscribing to a Service Bus queue or subscription.
