[jira] [Commented] (OAK-2675) Include change type information in perf logs for diff logic

--------------------------------------

[~catholicon] Do you think having this support would help in debugging/understanding observation performance issues better. Otherwise we can close it

> Currently the diff perf logs in {{NodeObserver}} does not indicate what type of change was processed i.e. was the change an internal one or an external one. 
> Having this information would allow us to determine how the cache is being used. For e.g. if we see slower number even for local changes then that would indicate that there is some issue with the diff cache and its not be being utilized effectively
