Hi Friends,
I am developing a Retry mechanism flow with the help of Timeout control node.
we are reading messages from a Queue, and before we send those messages to another process , each message need to be put on sleep for 1 minute. with the help of TimeoutConrol node we can acheive this .
We need to Process all messages from the input Queue at the earliest , and After reading messages each message should wait only 1 minute before sending to another process .We will be having heavy message traffic to the input Queue
If we use Timeout control node in the flow, will it create performance issue , like it will read only 1 message and then wait for 1 minute to read another message from the Queue ? .message flow will be hanged for 1 minute ? or is it based on the additional instance which we configure for the flow.
-------------
2) We also consider to use Queue expiry property to have a expiry in the message level .
Which one is better option ? MQ level message expiry or Timeout control node .
Kindly share your advises .

You need to reconsider this design.
Sleeping a full second for every message, regardless of whether it happens serially or paralellly, is an extreme performance impact in and of itself.
Particularly for 'heavy message traffic to the input queue".
Whatever the issue with the process you are calling, you need to fix that.
If you are attempting to write this flow as a patch for a problem with the downstream problem "until it can be fixed", then you need to raise this to as high a level of management as you can. " Until it can be fixed" never comes without a very large amount of pressure.
