I think this would probably require an update to the table `__init__.py` file, soemthing like this: ```python def scan_by_tag( self, tag_name: str, row_filter: Union[str, BooleanExpression] = ALWAYS_TRUE, selected_fields: Tuple[str, ...] = ("*",), case_sensitive: bool = True, options: Properties = EMPTY_DICT, limit: Optional[int] = None, ) -> DataScan: """ Fetch a DataScan for the snapshot referenced by the given tag. Args: tag_name: Name of the tag to scan row_filter: A string or BooleanExpression that describes the desired rows selected_fields: A tuple of strings representing the column names to return case_sensitive: If True column matching is case sensitive options: Additional Table properties as a dictionary of string key value pairs limit: An integer representing the number of rows to return Returns: A DataScan for the snapshot referenced by the given tag Raises: ValueError: If the tag does not exist or is not a valid tag """ snapshot_id = self.get_snapshot_id_by_tag(tag_name) return self.scan( row_filter=row_filter, selected_fields=selected_fields, case_sensitive=case_sensitive, snapshot_id=snapshot_id, options=options, limit=limit, ) def get_snapshot_id_by_tag(self, tag_name: str) -> int: """ Get the snapshot ID associated with a given tag. Args: tag_name (str): The name of the tag. Returns: int: The snapshot ID associated with the tag. Raises: ValueError: If the tag does not exist or is not a valid tag. """ ref = self._transaction.table_metadata.refs.get(tag_name) if ref is None or ref.snapshot_ref_type != SnapshotRefType.TAG: raise ValueError(f"Tag '{tag_name}' does not exist or is not a valid tag.") return ref.snapshot_id ``` @kevinjqliu @jayceslesar any thoughts? Im happy to add it, if it would be helpful. -- This is an automated message from the Apache Git Service.
