> We need to support transactional scan in SQL engine.
> At the moment, the transactional protocol has a restriction such that the scan must be issued on the node that initiated the transaction. This makes optimisations related to a distributed sql execution barely usable, but we will deal with this later. As a first step, let's just disable distribution trait in the planner to get local plans.
