Method

concatenateFeatureGroupData POST

Copy POST

Concatenates data from one Feature Group to another. Feature Groups can be merged if their schemas are compatible, they have the special `updateTimestampKey` column, and (if set) the `primaryKey` column. The second operand in the concatenate operation will be appended to the first operand (merge target).

Arguments:

REQUIRED	KEY	TYPE	DESCRIPTION
Yes	featureGroupId	str	The destination Feature Group.
Yes	sourceFeatureGroupId	str	The Feature Group to concatenate with the destination Feature Group.
No	mergeType	str	`UNION` or `INTERSECTION`.
No	replaceUntilTimestamp	int	The UNIX timestamp to specify the point until which we will replace data from the source Feature Group.
No	skipMaterialize	bool	If `True`, will not materialize the concatenated Feature Group.

Note: The arguments for the API methods follow camelCase but for Python SDK underscore_case is followed.

Response:

KEY	TYPE	DESCRIPTION
success	Boolean	true if the call succeeded, false if there was an error

Exceptions:

TYPE	WHEN
DataNotFoundError	`featureGroupId` is not found.
DataNotFoundError	`sourceFeatureGroupId` is not found.
