SHALLOW CLONE¶

Delta Lake supports SHALLOW CLONE clause in CREATE TABLE and REPLACE TABLE statements.

cloneTableHeader SHALLOW CLONE source temporalClause?
  (TBLPROPERTIES tableProps)?
  (LOCATION location)?

cloneTableHeader
    : createTableHeader
    | replaceTableHeader
    ;

createTableHeader
    : CREATE TABLE (IF NOT EXISTS)? table
    ;

replaceTableHeader
    : (CREATE OR)? REPLACE TABLE table
    ;

temporalClause
    : FOR? (SYSTEM_VERSION | VERSION) AS OF version
    | FOR? (SYSTEM_TIME | TIMESTAMP) AS OF timestamp
    ;

SHALLOW CLONE becomes a CloneTableStatement logical operator in a logical query plan that is resolved to a CreateDeltaTableCommand.
