Network.AWS.SQS.ChangeMessageVisibility
Description
Changes the visibility timeout of a specified message in a queue to a new value. The maximum allowed timeout value you can set the value to is 12 hours. This means you can't extend the timeout of a message in an existing queue to more than a total visibility timeout of 12 hours. (For more information visibility timeout, see Visibility Timeout in the Amazon SQSDeveloper Guide.)
For example, let's say you have a message and its default message visibility
timeout is 30 minutes. You could call ChangeMessageVisiblity with a value of
two hours and the effective timeout would be two hours and 30 minutes. When
that time comes near you could again extend the time out by calling
ChangeMessageVisiblity, but this time the maximum allowed timeout would be 9
hours and 30 minutes.
If you attempt to set the VisibilityTimeout to an amount more than the
maximum time left, Amazon SQS returns an error. It will not automatically
recalculate and increase the timeout to the maximum time remaining. Unlike
with a queue, when you change the visibility timeout for a specific message,
that timeout value is applied immediately but is not saved in memory for that
message. If you don't delete a message after it is received, the visibility
timeout for the message the next time it is received reverts to the original
timeout value, not the value you set with the ChangeMessageVisibility action.

Request lenses
cmvQueueUrl :: Lens' ChangeMessageVisibility Text Source
The URL of the Amazon SQS queue to take action on.
cmvReceiptHandle :: Lens' ChangeMessageVisibility Text Source
The receipt handle associated with the message whose visibility timeout
should be changed. This parameter is returned by the ReceiveMessage action.
cmvVisibilityTimeout :: Lens' ChangeMessageVisibility Int Source
The new value (in seconds - from 0 to 43200 - maximum 12 hours) for the message's visibility timeout.
