polars-deltalake
Native Polars I/O plugin for Delta Lake, backed by delta-kernel-rs.
import polars as pl
from polars_deltalake import scan_delta
lf = scan_delta("s3://bucket/path/to/table")
df = lf.filter(pl.col("region") == "eu").select("id", "value").collect()
The plugin pushes projection, slice (n_rows), and predicate filters into the kernel scan. Predicates that don't map to a kernel-supported shape fall back to Polars-side filtering after the scan.
scan_cdf streams a Delta table's Change Data Feed as a LazyFrame between two commit versions:
from polars_deltalake import scan_cdf
lf = scan_cdf("s3://bucket/path/to/table", start_version=10, end_version=20)
df = lf.filter(pl.col("_change_type") == "update_postimage").collect()
Output rows carry the table's columns plus _change_type, _commit_version, and _commit_timestamp. Requires delta.enableChangeDataFeed = true on the table.
