Ok, so i digged deeper in the problem and will try to describe it
We want to cache persistent objects and need cache to function exactly like
it is a DB in respect of javax.persistence.Transient annotated fields. Some
business logic is doing deep object cloning and it needs those
javax.persistence.Transient to be copied also. So we can't mark them with
transient keyword, nor use readResolve. We have huge domain with hundreds of
classes, i've looked into implementing BinarySerializer but this adds huge
amount of code which have to be maintained for each object having transient
fields. Same applies to Binarylizable plus it would add compile dependency
on Ignite which we want to keep as a pluggable option.
However small patch to ignite library seemd to solve my problems:

is there any chance Ignite can add support for handling
javax.persistence.Transient annotations?
