@Chowdhury-Anik just bumping this PR :) would love some tests please. |
This commit adds four data sink methods for Polars LazyFrame: - sink_parquet: Write LazyFrame to Parquet format - sink_csv: Write LazyFrame to CSV format - sink_ipc: Write LazyFrame to IPC/Feather format - sink_ndjson: Write LazyFrame to NDJSON format These sinks allow users to write LazyFrames directly without needing to call .collect() first, improving performance for large datasets. Fixes apache#791
