Is there any way in NiFi to add custom fields as part of the "search events" option in Data Provenance feature.

[#1]

The idea is to add search criteria based on custom field (part of the event) based on some unique identifier ( e.g. Order Number) . This will help in identifying the unique transaction details. Please suggest if there is any other alternatives to achieve this.

Yes in nifi.properties see the following properties:

# Comma-separated list of fields. Fields that are not indexed will not be searchable. Valid fields are:

# EventType, FlowFileUUID, Filename, TransitURI, ProcessorID, AlternateIdentifierURI, Relationship, Details nifi.provenance.repository.indexed.fields=EventType, FlowFileUUID, Filename, ProcessorID, Relationship

# FlowFile Attributes that should be indexed and made searchable. Some examples to consider are filename, uuid, mime.type nifi.provenance.repository.indexed.attributes=

I believe the ask was can we add "Custom Fields" eg; new fields other that the defined "valid" fields. How can I add pat or time stamp etc?
