Valid Q.. Came to my mind as well.. So the ans is the 1t write of the
cell to be done with a user who is having permission. (super user?)
While doing that write he has to give

Even if you don't set a grant permisison to a table for userX - you will be

I think for that I don't think we have any APIs. May be for now you may

1.Why is it better to have single file per region than multiple files for
read performance. Why can't multile threads read multiple file and give
better performance?

will never be allowed to write to the table, so I don't see how I
I verified the above behaviour using test case as the cluster was busy with
other activities.
So in the above example that you mentioned, you had already issued RW
