What is MQInput node?
The MQInput node receives a message from a WebSphere MQ message queue that is defined on the queue manager of the broker. The node uses MQGET to read a message from a specified queue, and establishes the processing environment for the message.
What are the nodes in IIB?

MQ simply stands for Message Queue. You would use one when you need to reliably send a inter-process/cross-platform/cross-application message that isn’t time dependent. The Message Queue receives the message, places it in the proper queue, and waits for the application to retrieve the message when ready.

What is transaction mode in MQInput node in IIB?

What is sync point in MQ?
A syncpoint is a logical point in the execution of a program where changes made by the program can be saved. The message request operates within the unit of work: the message is not visible outside the unit of work until the unit of work is saved. If the unit of work is rolled backed, then the message is deleted.
What is compute mode in IIB?
The value of the Compute Mode property specifies which new message trees are propagated from the Compute node. Therefore, for those message trees that are selected, the input messages are discarded unless they are explicitly copied into the new equivalent output message tree.
