Then the zarr devs can decide whether this use case is compatible with the zarr spec or not.,"{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,546562676

The scenario you are describing--trying to open a file that is not accessible at all from the client--is certainly not something we ever considered when designing this. It is a miracle to me that it does work with netCDF.

I think you are on track with the serialization diagnostics. I believe that @jhamman has the best understanding of this topic. He implemented the parallel mode in `open_mfdataset`. Perhaps he can give some suggestions.

In the meantime, it seems worth asking the obvious question...how hard would it be to mount the NFS volume on the client? That would avoid having to go down this route.

One clarification question: is there just a single zarr store you are trying to read? Or are you trying to combine multiple stores, like `open_mfdataset` does with multiple netcdf files?

> Some of the data is only available on the workers, not on the client. 

Can you provide more detail about how the zarr data is distributed across the different workers and client.
