Maxim Muzafarov commented on CASSANDRA-15254:
---------------------------------------------

[~dcapwell] thank you! I think we are on the same page for now, I'll prepare PR 
according to everything we discussed here.

 

Of course, the JMX itself remains unchanged. I mean, some kind of refactoring 
needs to be done to handle the configuration changes for some of the Config's 
properties that might perform actions before and after changing the property 
value and make them handled for the same things by onBeforeChange, 
onAfterChange listener calls. Of course, I don't know the number of changes as 
we have about 345 configuration fields to check, so I suggested breaking the 
patch into small ones. I will check the details and get back here.
