Thanks.
> 1. Why are we not using durable_unlink instead of unlink to remove the partial tmp files?
durable_unlink() issues fsync on the parent directory, if used, those fsync() calls will be per partial.tmp file. Moreover, durable_unlink() is backend-only, not available for tools i.e. FRONTEND code. If we don't durably remove the pratial.tmp file, it will get deleted in the next cycle anyways, so no problem there.
