Polars Integration with Remote Storage

Polars has native cloud storage support via multiple backends, plus integration with fsspec and PyArrow filesystems.

Native Cloud Access (object_store)

Polars uses the Rust object_store crate internally for direct cloud URI access:

import polars as pl

# Read from cloud URIs directly (s3://, gs://, az://)
df = pl.read_parquet("s3://bucket/data/file.parquet")
df = pl.read_parquet("gs://bucket/data/file.parquet")
df = pl.read_csv("s3://bucket/data/file.csv.gz", infer_schema_length=1000)
