> Currently. bootstrap REPL LOAD have added checkpoint identifiers in
> DB/table/partition object properties once the data/metadata related to the
> object is successfully loaded.
> If the Db exist and is not empty, then currently we are throwing exception.
> But need to support it for the retry scenario after a failure.
> If there is a retry of bootstrap load using the same dump, then instead of
> throwing error, we should check if any of the tables/partitions are
> completely loaded using the checkpoint identifiers. If yes, then skip it or
> else drop/create them again.
> If the bootstrap load is performed using different dump, then it should throw
> exception.
> Allow bootstrap on empty Db only if ckpt property is not set. Also, if
> bootstrap load is completed on the target Db, then shouldn't allow bootstrap
> retry at all.
