[jira] [Created] (NIFI-11627) Add Dynamic Schema References to ValidateJSON Processor

Chuck Tilly created NIFI-11627:
----------------------------------

             Summary: Add Dynamic Schema References to ValidateJSON Processor
                 Key: NIFI-11627
                 URL: https://issues.apache.org/jira/browse/NIFI-11627
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
    Affects Versions: 1.19.1
            Reporter: Chuck Tilly


For the ValidateJSON processor, add support for flowfile attribute references that will allow for a JSON schema located in the Parameter Contexts, to be referenced dynamically based on a flowfile attribute. e.g. 
{code:java}
#{${schema.name}} {code}
 

The benefits of adding support for attribute references are significant.  Adding this capability will allow a single processor to be used for all JSON schema validation.  Unfortunately, the current version of this processor requires a dedicated processor for every schema, i.e. 12 schemas requires 12 ValidateJSON processors.  This is very laborious to construct and maintain, and resource expensive.
