Description
Experience Level: Intermediate
General information for the business: Data integration
Description of every module: I need a Apache Nifi Processor, that can modify the JSON payload of a flowfile
There are two ways to solve it, either write an own processor or use the JOLT processor and extend the JOLT library with the additional functionality
Description of requirements/functionality: - rename attributes
- remove attributes
- add attributes with constant values
- add attributes with the result of an expression (JSONPath or similar)
- reformat existing values of attributes
- map values of attributes (replace matching values)
- flatten arrays of values to a single string
- add attributes with hash value of given list of other attributes
Specific technologies required: Java, Nifi
Extra notes: there is a great sample available, which provides a good template
https://github.com/bbende/nifi-example-bundles/blob/master/nifi-example-utils-bundle/nifi-example-utils-processors/src/main/java/org/apache/nifi/processors/example/utils/RenameJSONFields.java
some intro into JOLTTransformation in Nifi can be found here
https://community.hortonworks.com/articles/44726/json-to-json-simplified-with-apache-nifi-and-jolt.html
the code has to be integrated into an existing gitlab project and a NAR has to be provided
