class AxisDefinition(keys: list[str], chunking: Chunking | Chunking)#

Defines which axis from a MARS Request form an axis in the Zarr array.

Also defines if the data is to be chunked.

Parameters:

  • keys (list of str) – mars keys that for this axis.

  • chunking (Chunking) – Define how this axis shall be chunked

Bases: enum.Enum

Defines how an axis will be chunked.

WHOLE_AXIS#

The entire axis is a single chunk; accessing any value loads all values on that axis.

SINGLE_VALUE#

Each value along the axis is its own chunk.

FixedSizeChunk#

Groups every chunkShape consecutive values into one chunk.
