Vladimir Ozerov commented on IGNITE-5736:
-----------------------------------------
[~daradurvs], Ignite doesn't support compatibility between releases, so I am
not sure what is the goal if this task. I think these changes will not be
included into the product. All we need is a flag on configuration {e.g.
BinaryConfiguration), which will control whether we write values as varint or
not. It should be {{false}} by default, so that new Ignite has chances to start
on persistent data produced by previous version.
I propose to close both IGNITE-5732 and IGNITE-5736 as "Won't Fix" and focus on
implementation itself.
