> 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.
