> h2. Use Case
> * User starts up cluster of N nodes and fills it with some data.
> * User splits the cluster into two halves and modifies data in each half
> independently.
> * User tries to join two halves back into one - irresolvable conflicts in
> data for the same key may happen.
> h2. BaselineTopology Versioning
> Each BLT contains enough information to check its compatibility with other
> BLT. If BLT of joining node is not compatible with BLT grid is working on at
> the moment, node is not allowed to join the grid and must fail with proper
> exception.
