> when "hive.repl.dump.metadata.only.for.external.table" = true is used in repl dump, we only dump metadata for external tables. partitioned external tables currently on the load side load one partition at a time, even though HMS has an api for bulk partition update. we should for such scenarios use the bulk api. this will significantly improve performance during bootstrap phase.
