> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Major
> Fix For: 1.20.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When we export a flow for download, we have to serialize any referenced
> Parameter Context as part of the JSON. To do this, we build up a collection
> of VersionedParameterContexts. The logic that we use does this for every
> Process Group. So if we have many small Process Groups, each bound to a
> Parameter Context, we formulate that VersionedParameterContext every time.
> However, there is no need to create more than one VersionedParameterContext
> for each existing ParameterContext. This mapping becomes very expensive and
> can take many minutes for flows that contain lots of Parameters and lots of
> Process Groups.
