cozip
Python bindings for libcozip. Read a Cloud-Optimized ZIP archive's manifest over HTTP range requests, or write one from a pyarrow Table.
The native libcozip binary ships inside the wheel, no C toolchain required.
Install
pip install cozip
Usage
Write
import cozip
import pyarrow as pa
table = pa.table({
"name": ["a.txt", "b.bin"],
"path": ["/path/to/a.txt", "/path/to/b.bin"],
})
cozip.write("out.zip", table)
name is how each file appears inside the archive. path is where it lives on disk, used at write time and dropped from the manifest. Any extra columns ride along into __metadata__ and become queryable on read.
Names stored in the archive must be ASCII. Local source and output paths may contain Unicode. Empty files are not valid cozip entries; the writer rejects them before replacing the output.
table = pa.table({
"name": ["a.tif", "b.tif"],
"path": ["/path/to/a.tif", "/path/to/b.tif"],
"cloud_pct": [12.3, 45.1],
})
cozip.write("out.zip", table)
Read
import cozip
manifest = cozip.read("https://example.com/dataset.zip")
train = manifest[manifest["split"] == "train"]
manifest is a pandas DataFrame: name, offset, size, cozip:location, and the writer's extras. Local path or URL, same call. It fetches the byte-0 index and __metadata__, never the payloads.
columns=[...] picks extras. location=False drops cozip:location.
cozip.read() supports only Flat-profile archives (profile = 1). TACO
archives (profile = 2) and all other profiles are rejected.
