[jira] [Commented] (MINIFI-171) Dynamic Properties support for
processors
[ https://issues.apache.org/jira/browse/MINIFI-171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15793759#comment-15793759 ]

GitHub user jdye64 opened a pull request:

MINIFI-171 Dynamic Properties support for processors
Added support in Processor.cpp to both set and get dynamic properties.
The logic will first attempt to set the parsed Property from the .yml
file as a supported property. IF that parsed Property is not in the
whitelisted supported list AND if the “nifi.accept.dynamic.properties”
configuration is set to true then the Property will be added to a
Map<String, Property> of dynamic properties that can be accessed in a
manner similar to the supported properties from any processor logic
that extends Processor.cpp

> Currently any Property read from the config.yml file that is not explicitly defined in the processor's implementation will be ignored by Processor.cpp when reading the configurations. This prevents any dynamic property from being defined in the config.yml and passed to the processor at runtime. Certain processors rely heavily on the concept of dynamic properties that are passed to them at runtime to handle things like setting dynamic properties based on properties that are declared. All of these possibilities cannot be handled upfront so there should be a mechanism, most likely in Processor.cpp, that allows for a list of dynamicProperties that are parsed form the config.yml file to be stored and accessed by the underlying processor implementation at runtime and use them as the processor desires.
