Dear Julia community,
we are looking for a object-storage compatible file format for quite large dense N-dimensional arrays. Our project partners suggested this http://zarr.readthedocs.io/en/stable/ format, but there seems to be only a python implementation. I am a bit afraid of the overhead that PyCall would add for every read/write so my question is if you know of alternative formats that already have a Julia wrapper or at least a C API that could be wrapped.
Thanks already for your suggestions
