Daniel Stieglitz commented on NIFI-11627:
-----------------------------------------
[~exceptionfactory] I would like to clarify I am not actually creating a
SchemaRegistry. I am trying to integrate the use of one. As a result I need to
use SchemaAccesStrategy which involves returning the schema in a RecordSchema
object. Since the schema is now accessed via a SchemaAccesStrategy I have had
to make an anonymous SchemaAccesStrategy to encapsulate the current
functionality of obtaining the JSON schema from a resource. That is where I
stored the contents of the JSON schema in the text section of
SimpleRecordSchema. I assume (but not tested just yet) that the various Schema
Registry implementations return the actual text of the schema also. Hence I
would like to take advantage of that and build the necessary JSON Schema object
for validation. I have been able to reuse much of the code found in
SchemaAccessUtils to accomplish the integration of a SchemaRegistry. Please let
me know if there is still an issue with this design. Thanks!
> 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
> Assignee: Daniel Stieglitz
> Priority: Major
>
> 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.
