[Tarantool-patches] [PATCH v3 0/2] vinyl: rework upsert operation

[Vladislav Shpilevoy]

Hi! Thanks for the patchset!

Does this patchset change format of vinyl statements on disk? If yes, I guess
it breaks backward compatibility. Did you check how does it behave when booted
from files of a previous version? Does it crash? Does it report an error? How
a user can upgrade his vinyl files to the new format?
