Hi Abhishek,
Do you mean
this thread about Code Coverage API plugin?
If yes, I'd guess your original message got merged (same title).
If you mean another thread, please let me know the time when you sent it.
If you are interested in the Role Strategy plugin, my suggestion would be to start from trying it on a Jenkins instance. I have a
demo which allows to get the first setup running quickly. If you want to try performance/UX, it could be a good start to fork this demo and to create a more sophisticated Role Strategy setup with many roles, complex patterns and assignments.
Hopefully it helps,
Oleg
