sedonadb-zarr 0.4.0

No project description provided

sedonadb-zarr

Zarr support for SedonaDB as an opt-in plugin package. Reads Zarr v3 groups (with sharding, vlen-utf8 dims, etc.) as a column of N-D rasters:

import sedona.db
from sedonadb_zarr import ZarrExtension

sd = sedona.db.connect()
sd.register(ZarrExtension())
sd.read("file:///path/to/foo.zarr").show()

The main sedonadb package does not bundle Zarr support — applications that don't import sedonadb_zarr pay no runtime cost.

Architecture

A maturin-built mixed Rust/Python package. The Rust side is a thin PyO3 shim around sedona-raster-zarr exposing PyZarrChunkReader (implementing __arrow_c_stream__).
