Zarr Chunked Array Store Starter

Use this skill to convert a small numeric matrix into a chunked, compressed Zarr store and inspect a deterministic summary of its layout.

What This Skill Does

• reads a toy tabular matrix
• writes a local Zarr v2 array with fixed chunking and Blosc compression
• reports shape, chunk layout, compressor choice, and summary statistics

When To Use It

• when you need a starter for chunking-sharding
• when you want a repo-local example of Zarr plus numcodecs
• when you need a tiny test fixture for chunked scientific array storage

Run

python3 skills/data-acquisition-and-dataset-handling/zarr-chunked-array-store-starter/scripts/run_zarr_chunked_array_store.py --input skills/data-acquisition-and-dataset-handling/zarr-chunked-array-store-starter/examples/toy_matrix.tsv --store-out scratch/zarr/toy_matrix.zarr --summary-out scratch/zarr/toy_matrix_summary.json

Notes

• The starter writes Zarr format 2 explicitly so classic compressor settings remain deterministic.
• The example is intentionally tiny and local; scale chunking decisions against real workloads before production use.
