> Replicated TX cache, nodes A, B, C
> 0. A and B have topology 2, C already got topology 3
> 1. A sends prepare with topology 2 to B and C, both apply the prepare and respond
> 2. C forwards prepare to B with topology 3
> 3. A sends commit with topology 2 to B and C, both commit and respond
> 4. again, C forwards prepare to B with topology 3
> 5. A and B get updated topology id
> 6. A executes another transaction on the same entry
> 7. prepare and commit from first transaction with topology 3 arrive at B - B overwrites (or removes) the entry again
> Result: on B we have inconsistent state
