Overview: Quilt: Constructor

Quilt.__init__(bus, *, axis=0, retain_labels, axis_hierarchy=None, axis_opposite=None, deepcopy_from_bus=False)[source]

Parameters:

bus – Bus of Frame to be used for virtual concatenation.
axis – Integer specifying axis of virtual concatenation, where 0 is vertically (stacking rows) and 1 is horizontally (extending columns).
retain_labels – Boolean to determine if, along the axis of virtual concatentation, if component Frame labels should be used to form the outer depth of an IndexHierarchy. This is required to be True if component Frame labels are not globally unique along the axis of concatenation.
deepcopy_from_bus – Boolean to determine if containers are deep-copied from the contained Bus during extraction. Set to True to avoid holding references from the Bus.

classmethod Quilt.from_duckdb(fp, *, config=None, axis=0, retain_labels, deepcopy_from_bus=False, max_persist=None)[source]

Given a file path to an DuckDB Quilt store, return a Quilt instance.

Parameters:

fp – A string file path or Path instance.
config – A StoreConfig, or a mapping of label ot StoreConfig
axis – Integer specifying axis of virtual concatenation, where 0 is vertically (stacking rows) and 1 is horizontally (extending columns).
retain_labels – Boolean to determine if, along the axis of virtual concatentation, if component Frame labels should be used to form the outer depth of an IndexHierarchy. This is required to be True if component Frame labels are not globally unique along the axis of concatenation.
deepcopy_from_bus – Boolean to determine if containers are deep-copied from the contained Bus during extraction. Set to True to avoid holding references from the Bus.
max_persist – When loading Frame from a Store, optionally define the maximum number of Frame to remain in the Bus, regardless of the size of the Bus. If more than max_persist number of Frame are loaded, least-recently loaded Frame will be replaced by FrameDeferred. A max_persist of 1, for example, permits reading one Frame at a time without ever holding in memory more than 1 Frame.

classmethod Quilt.from_zip_npz(fp, *, config=None, axis=0, retain_labels, deepcopy_from_bus=False, max_persist=None)[source]

Given a file path to zipped NPZ Quilt store, return a Quilt instance.

Parameters:

fp – A string file path or Path instance.
config – A StoreConfig, or a mapping of label ot StoreConfig
axis – Integer specifying axis of virtual concatenation, where 0 is vertically (stacking rows) and 1 is horizontally (extending columns).
retain_labels – Boolean to determine if, along the axis of virtual concatentation, if component Frame labels should be used to form the outer depth of an IndexHierarchy. This is required to be True if component Frame labels are not globally unique along the axis of concatenation.
deepcopy_from_bus – Boolean to determine if containers are deep-copied from the contained Bus during extraction. Set to True to avoid holding references from the Bus.
max_persist – When loading Frame from a Store, optionally define the maximum number of Frame to remain in the Bus, regardless of the size of the Bus. If more than max_persist number of Frame are loaded, least-recently loaded Frame will be replaced by FrameDeferred. A max_persist of 1, for example, permits reading one Frame at a time without ever holding in memory more than 1 Frame.
