Zarr is a Julia package providing an implementation of chunked, compressed, N-dimensional arrays. Zarr is originally a Python package. In Zarr we aim to implement the zarr spec.

Documentation Build Status

Package status

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.

Quick start

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")
