Piotr Jastrzebski commented on CASSANDRA-9988:
----------------------------------------------
What do you mean by efficient method dispatch? Could you please explain me why
having two implementations of an interface will result in faster method
invocations (if that's what you have in mind) than when having three
implementations? I know that implementing too many interfaces can have negative
impact on performance due to collisions in method offsets but I never heard
that number of implementations has any performance impact.

> In many cases we have small btrees, small enough to fit in a single leaf
> page. In this case it _may_ be more efficient to specialise our iterator.
