             Summary: Add Registered Flow Snapshot Metadata to Process Group 
Status
                 Key: NIP-8
                 URL: https://issues.apache.org/jira/browse/NIP-8
             Project: NiFi Improvement Proposal
          Issue Type: Improvement
            Reporter: Pierre Villard


h3. Title

Adding Registered Flow Snapshot Metadata to Process Group Status
h3. Motivation

In ProcessGroupStatus, we already have the information for Versioned Flow State 
that tells us what is the versioning state of the process group (when 
versioned). The goal is to not limit ourselves to this information and also add 
the RegisteredFlowSnapshotMetadata information to make available the versioning 
information when the process group is versioned (flow identifier, version, etc).

We don't want to add this information as part of the DTOs (as we already have 
this information in the UI through different APIs) but rather have this 
information populated in AbstractEventAccess so that it can be leveraged by the 
implementations of the StatusHistoryRepository interface.
h3. Scope

Add
{code:java}
    private RegisteredFlowSnapshotMetadata registeredFlowSnapshotMetadata; 
{code}
to ProcessGroupStatus in nifi-api with appropriate getter/setter.
h3. Compatibility

Fully backward compatible.
