> Currently. bootstrap REPL LOAD expect the target database to be empty or not exist to start bootstrap load.
> But, this adds overhead when there is a failure in between bootstrap load and there is no way to resume it from where it fails. So, it is needed to create checkpoints in table/partitions to skip the completely loaded objects.
> Use hash of the fully qualified path of the dump directory as a checkpoint identifier. This should be added to the table / partition properties in hive via a task, as the last task in the DAG for table / partition creation.
