> Currently, query execution pipeline is implemented as chain of multiple
> stages of completable futures with context passed partially as result of a
> stage and partially as capture of stage closure. Such an approach makes it
> hard to rewind execution to a particular stage and retry query execution with
> updated input.
> Need to rework execution pipeline. The only requirement is to make it easy to
> clean up query execution state and retry operation once again from the middle
> of query execution pipeline (i.e. discard current plan and retry execution
> from PLANNING phase when time of implicit transaction started on the next
> stage refers to a newer version of catalog).
