Description

Currently, we change QueryPlan.outputs at execution time of DDLTask, MoveTask. The post execution hook relies on QueryPlan.outputs to log the changed entities.

This makes the serialization hard, because we need to serialize the outputs when each of the Tasks are done. This is even harder given that we allow parallel execution of tasks now.

We should be able to determine all that at compile time.
