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

Thanks, the main purpose is to use rio-tiler to read zarr from the cloud to implement dynamic tile service. Looking forward to your plan!
