10. What Is the Pipeline?
Answer:
The pipeline is the general term used to refer to the data structure in which input and output values are maintained for a flow service. It allows services in the flow to share data.The pipeline starts with the input to the flow service and collects inputs and outputs from subsequent services in the flow. When a service in the flow executes, it has access to all data in the pipeline at that point.

Outside the catch block put a branch on that variable or flag and if it is non-null then exit with failure or call the service that generates the exception.
35. How Should I Organise Connection Pools?
Answer :
If you have adapter notifications and adapter services then you will need to have two separate connections. Otherwise you may get strange errors about transactions and the like. You should also avoid having connection pools shared across different functional areas, even if they are pointing to the same database. The reason for this is that tuning the size of the pool becomes quite difficult if you have multiple types of usage of a pool. You are also unable to easily change the database settings for one without impacting on the other.
One approach that seems to work quite well is to have separate pools for each package (generally.. not a hard and fast rule though), as your packages should generally be divided up according to functional area too.

Answer :
Set the “$merge” variable in restorePipeline or “merge” in restorePipelineFromFile to be true. This will ensure that everything in the pipeline before a restorePipeline step is preserved.

$loop will be assumed, and a com.wm.lang.flow.FlowException will be thrown if the EXIT is not in a LOOP
