Summary: Add Registered Flow Identifier and Version Path to MDC
Attributes
Key: NIFI-15860
URL: https://issues.apache.org/jira/browse/NIFI-15860
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Reporter: David Handermann
Assignee: David Handermann
The Logging Attributes for Process Groups can contain Registered Flow
Identifier and Registered Flow Version attributes when the group is under
version control. This enables traceability to current version control
information for Processors in the group. However, for larger Process Groups
with one or more child Process Groups, the Registered Flow attributes are not
present.
Following the pattern of the Process Group ID Path and Process Group Name Path
attributes, a new attribute should be added that contains the Flow Identifier
and Version information in a hierarchical path structure. Process Groups that
do not have Version Control Information should use a placeholder of
{{{}UNREGISTERED{}}}. Process Groups under version control should include both
the Flow Identifier and Version in the path segment, separated by a colon
character.
A child Process Group nested under a versioned Process Group should produce a
path value as follow:
{noformat}
/12345678-1234-1234-1234-123456789012:1.0.0/UNREGISTERED
{noformat}
Based on this pattern, the path segment index follows the same structure as the
Process Group ID and Name Paths.
