  • ZERO-COPY CLONE OF DYNAMIC TABLES
    Publication number: 20250328545
    Abstract: Provided herein are systems and methods for a zero-copy clone of a DT. A method includes performing a clone operation on a dynamic table (DT) to generate a cloned DT. The DT is based on a query applied on a base table. The cloned DT is based on the query applied on a cloned base table corresponding to the base table. A first delta is determined based on at least one change in the base table between a first version of the base table used by the DT at a time of the clone operation and a second version of the base table generated prior to the clone operation. A first refresh operation of the cloned DT is performed based on the first delta.
