Description

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.
