If a result is returned by the LookupService, that result is optionally added to the Record. In this case, the processor functions as an Enrichment processor. Regardless, the Record is then routed to either the 'matched' relationship or 'unmatched' relationship (if the 'Routing Strategy' property is configured to do so), indicating whether or not a result was returned by the LookupService, allowing the processor to also function as a Routing processor. The "c oordinates" to use for looking up a value in the Lookup Service are defined by adding a user-defined property. Each property that is added will have an entry added to a Map, where the name of the property becomes the Map Key and the value returned by the RecordPath becomes the value for that key. If multiple values are returned by the RecordPath, then the Record will be routed to the 'unmatched' relationship (or 'success', depending on the 'Routing Strategy' property's configuration). If one or more fields match the Result RecordPath, all fields that match will be updated. If there is no match in the configured LookupService, then no fields will be updated. I.e., it will not overwrite an existing value in the Record with a null value. Please note, however, that if the results returned by the LookupService are not accounted for in your schema (specifically, the schema that is configured for your Record Writer) then the fields will not be written out to the FlowFile.</p><h3>Tags: </h3 ><p>lookup, enrichment, route, record, csv, json, avro, logs, convert, >filter</p><h3>Properties: </h3><p>In the list below, the names of required >properties appear in <strong>bold</strong>.
