Zero-copy clones initially share the source table’s micro-partitions and represent an unchanged point-in-time copy; creating a dataset with transformed live data requires materializing the transformed results. Cloning is also not a cross-account writable-copy mechanism. Secure Data Sharing between accounts transfers no data but provides imported objects as read-only, so developers who need a writable dataset in a separate account need data to be copied or otherwise materialized there.
