Sure, I wanted to do that too. Will look and see where I can improve further

[deepthi912]

@Jackie-Jiang I noticed that registery, pipeline have static methods which are used by some of the classes. These static methods are calling RecordEnricherFactory which is again implemented by function and clp Enricher classes. I tried to check if I could squeeze in anywhere but no right spot. Not sure if by just removing RecordEnricher, we can make any big difference in refactoring though.

[Jackie-Jiang]

Basically the idea is to re-do #12243 and integrate CLP transform as a RecordTransformer
