Resumable Pipelines suspend th= e flow of data when an endpoint becomes inaccessible. If an exception disab= les a target endpoint, the Resumable Pipeline's execution state is saved in= the Snaplex nodes. After restoring connectivity to the target endpoin= t, you can resume the suspended Pipeline starting at the point of failure, = so that successfully processed documents are not processed again.
Every Snap in a Resumable Pipeline runs to completion before any of its = output documents are passed to the next downstream Snap. In contrast, a Sna= p in a standard Pipeline passes the document to the next downstream Sn= ap, possibly even before the first Snap completes its document processing.<= /p>
The SnapLogic Monitoring Dashboard displays the status = of Pipelines. If a Pipeline is suspended, the Snaps that have completed exe= cution are displayed in green, and the remaining Snaps are displayed in ora= nge.
You can resume a suspended Pipeline from the SnapLogic Dashboard.
Your Org must be subscribed to Resumable Pipelines to use this feature.<= /p>
In SnapLogic Designer, select the target Pi= peline and open the Properties menu. You can enable R= esumable Mode in existing Pipelines.
By default, the Error Pipeline option is disabled = and incompatible with Resumable Pipelines.
In SnapLogic Designer, if Snaps in your Resumable Pipeline turn orange, = then your Pipeline is suspended. You can also configure a Task to send= an email when it goes into the Suspended state. To view status of a R= esumable Pipeline, go to the Dashboard.
The Status column displays the following additional states for Resumable= Pipelines.
You can resume suspended Pipelines after the endpoint is restored by sel= ecting the Pipeline and clicking the Resume icon ().&= nbsp;If you click the Stop icon (),= then the execution state is deleted from the nodes and that execution is n= o longer be able to resume. Additionally, you cannot manually suspend a Res= umable Pipeline.
The Resumable Pipeline feature is best implemented along the lines of th= e following use case.
A Pipeline Execute Snap, inside= an Ultra Pipeline Task, calls= the Resumable Pipeline.
=
This Resumable Pipeline contains two concurrent services are processing = documents to be joined together and mapped.
= p>
An error occurs in one of the Snaps, so the remaining Snaps, which have = not been executed, turn orange to indicate their suspended state in the Pip= eline.
The Dashboard shows one error document in the Pipeline = Execute Snap inside the parent Pipeline that indicates an error occurred.= p>
The Extra Details tab includes a history of states for = the Resumable Pipeline.
