- Issues
- Add a "not null" semantic to schemas (e.g., `pl.NotNullType(pl.Float32)`)
- Visualization with Seaborn
- Change `pl.date_range(...)` error message to suggest `pl.date_ranges(...)` when passed an `Expr` (in a `with_columns(...)` call)
- slice is not respected in the sense that apparently the whole file is loaded first. This results for me in OOM and a longer than expected time.
- Add support for HDFS to `scan_parquet`
- Use parquet statistics when collecting column statistics from scanned parquet
- Excessive Memory Consumption During Rolling Operations on Large DataFrames
- `dt.total_nanoseconds` and `dt.total_microseconds` may overflow silently
- exception thrown if converting chunked arrow Table with struct and dictionary columns to polar Dataframe
- Align decimals (Int128) during IPC writes to enable zero-copy reads
