> Since we run in to the possibility of creating a large number tasks during
> replication bootstrap dump
> * we may not be able to hold all of them in memory for really large
> databases, which might not hold true once we complete HIVE-16892
> * Also a compile time lock is taken such that only one query is run in this
> phase which in replication bootstrap scenario is going to be a very long
> running task and hence moving it to execution phase will limit the lock
> period in compile phase.
