Indexing, which enable a subset of data items to be extracted or updated in anĪrray without loading the entire array into memory. Internally Zarr uses JSON to store array attributes, so attribute values must beĪs of version 2.2, Zarr arrays support several methods for advanced or “fancy” info Name : /foo/baz Type : Data type : float32 Shape : (1000, 1000) Chunk shape : (100, 100) Order : C Read-only : False Compressor : Blosc(cname='lz4', clevel=5, shuffle=SHUFFLE, blocksize=0) Store type : No.
