The package currently implements basic functionality for reading and writing zarr arrays. However, the package is under active development, since many compressors and backends supported by the python implementation are still missing.
using Zarr
z1 = zcreate(Int, 10000,10000,path = "data/example.zarr",chunks=(1000, 1000))
z1[:] .= 42
z1[:,1] = 1:10000
z1[1,:] = 1:10000
z2 = zopen("data/example.zarr")
z2[1:10,1:10]
