Outputting data products as zip stores as opposed to hdf5 serialization results in substantial reductions in file size, which may be meaningful when transferring files over networks or making copies. Files can be pretty easily read and written anndata and zarr like:

import zarr
import anndata
store = zarr.storage.ZipStore(file_path)
adata = anndata.read_zarr(store)

or

import zarr
import anndata
store = zarr.storage.ZipStore(file_path)
adata = anndata.AnnData()
adata = anndata.write_zarr(store)
