How to read zarr?

[Break00]

import xarray as xr
import zarr
from rio_tiler.io import COGReader

read zarr

ds = xr.open_zarr(r'D:\work\data\test.zarr')

I want to read zarr by COGReader, but Error !!!

with COGReader(None,dataset=ds) as image:
img = image.read()

Rio-tiler only accept rasterio object not fsspec ones.

Have a look on the cogeotiff/rio-tiler-fs project

Also there is no guarantee that rio-tiler will fully support Zarr dataset because GDAL support is somehow complicated (it splits the dataset in subdataset only for dataset with more than 2 dim)

See #453

Edit: oh I miss read what you were doing, but almost the same answer rio-tiler only accept rasterio object not xarray ones

I'm planning to support Zarr at some point but the specification and GDAL native support makes it non trivial
