Subject Re: Ignite 2.0 tasks/roadmap
Date Tue, 17 Jan 2017 16:35:32 GMT
Guys,

Do you think there is any reason to keep optimized marshaller on public API
in Ignite 2.0? It has several disadvantages, the major being non-conformant
with Java serialization guarantees(namely, the inability to add/remove
fields). On the other hand, Binary marshaller supports all this and much
more, and as fast as optimized.

Given that Binary marshaller rolls back to optimized in case of
Externalizable or presence of writeReplace/readResolve, I think it makes
sense just to move it to the private package.

Another positive effect - this will almost halve the number of test suites
we need to run on TC.

Thoughts?
