> ExportSnapshot need to copy snapshot manifest to destination cluster first, then setOwner and setPermission for those paths. But it's done with one thread, which lead to a long time to submit the job if your snapshot is big. I tried to make them processing in parallel, which can reduce the total time of submitting dramatically.
