Hello, igniters.
After a long and hard work I've finally pushed the IEP
<https://cwiki.apache.org/confluence/display/IGNITE/IEP-91%3A+Transaction+protocol>

Any useful feedback would be greatly appreciated.

Folks,
I've prepared a PR implementing my vision of public transactions API.
API is very simple and similar to Ignite 2, but has some differences.

I've made a small mistake above, the correct sentence is
void stop(); // Stop a component. Invoked in "depends on" relation order.
In the example above, RaftGroup is stopped before the Network.

But it looks like we do not need methods *readOnly *and *inactive*.
What is the point in adding them ?

using rebalancing as a first step.
Next step can be online in-place re-encryption. It's important to measure
business impact from it on online grid.

Folks,
I've almost finished a patch bringing some improvements to the data loss
handling code, and I wish to discuss proposed changes with the community
