-------------------------------------
Summary: FlowDifferenceFilters - handle splitRelationship()
Key: NIFI-15011
URL: https://issues.apache.org/jira/browse/NIFI-15011
Project: Apache NiFi
Issue Type: Improvement
Reporter: Pierre Villard
Assignee: Pierre Villard
Consider something like:
{code:java}
@Override
public void migrateRelationships(final RelationshipConfiguration config) {
if (!config.hasRelationship(B)) {
config.splitRelationship(A.getName(), A.getName(), B.getName());
}
super.migrateRelationships(config);
}{code}
Then I'd see a local change such as:
Selected Relationships Changed - From '[A]' to '[A, B]'
If the relation B didn't exist at all in the flow definition, and if the source
processor does not support dynamic relationships, then this change should not
show as a local change.
Similarly, if the processor does not support dynamic relationships and if we
have:
{code:java}
@Override
public void migrateRelationships(final RelationshipConfiguration config) {
if (!config.hasRelationship(A)) {
config.splitRelationship(OLD.getName(), A.getName(), B.getName());
}
super.migrateRelationships(config);
}{code}
(we remove an OLD relationship that we split into two new ones)
We should not show a local change like:
Selected Relationships Changed - From '[OLD]' to '[A, B]'
