Why our functional interfaces are serializable?

Folks,

We have more than 1500 classes (mostly anonymous) implementing functional
interfaces. Most common are *IgnitePredicate*, *IgniteClosure*, etc..

Question: why these interfaces are Serializable? A lot of classes which
implement these interfaces are never meant to be serialized.

I propose to remove Serializable from all functional interfaces.

Vladimir.

I would agree only for internal Ignite classes. If we touch public classes,
we risk breaking backward compatibility.

Agree, but we use some of them on public API for distributed operations and
they have to be Serializable.
