> At the moment we have a lot of various cached stuff used for different SQL types (prepared statements for local queries, two-step queries for distributed queries, update plan for DML). 
> What we need instead of having multiple caches is to create common execution plan for every query, which will hold both DML and SELECT stuff. Approximate content of such a plan:
> # Two-step plan
> # DML plan 
> # Partition pruning stuff
> # May be even cached physical node distribution (for reduce queries) for the given {{AffinityTopologyVersion}}
> # Probably {{AffinityTopologyVersion}}
> Then we will perform a single plan lookup/build per every query execution. In future we will probably display these plans in SQL views.
