Relevance of savepoints support inside of Ignite Transactions

[Dmitrii Ryabov]

Hi, Igniters!

I have an implementation for savepoints support inside of transactions,
which was reviewed by Boikov a year ago.

It allows us to rollback piece of the transaction, not whole tx.

Current restrictions:

* Doesn't work with near caches.

* MVCC should be disabled.



MVCC was merged recently.

So, I want to know – is ticket actual now?
