zarr_checksum
Algorithms for calculating a zarr checksum against local or cloud storage
Install
pip install zarr-checksum
Usage
CLI
To calculate the checksum for a local zarr archive
zarrsum local <directory>
To calculate the checksum for a remote (S3) zarr archive
zarrsum remote s3://your_bucket/prefix_to_zarr
Python
To calculate the checksum for a local zarr archive
from zarr_checksum import compute_zarr_checksum
from zarr_checksum.generators import yield_files_local, yield_files_s3
# Local
checksum = compute_zarr_checksum(yield_files_local("local_path"))
# Remote
checksum = compute_zarr_checksum(
yield_files_s3(
bucket="your_bucket",
prefix="prefix_to_zarr",
# Credentials can also be passed via environment variables
credentials={
aws_access_key_id: "youraccesskey",
aws_secret_access_key: "yoursecretkey",
region_name: "us-east-1",
}
)
