             Summary: Split and map functions in NiFi Expression Language
                 Key: NIFI-7763
                 URL: https://issues.apache.org/jira/browse/NIFI-7763
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Malthe Borch


This is a proposal to extend the NiFi Expression Language with functions {{split}} and {{map}} that combine to allow expression such as:

{{${keys:split(","):map(key => "t1.${key} = t2.${key}"):join(" and ")}}}

That is, split the {{keys}} attribute and dynamically create a join condition based on a set of primary keys.
