Polars Pipeline

Design study—not a runnable ETLantic 0.18 API guide. Prefer CAPABILITIES and examples/.

This page previously contained aspirational copy-paste code (including deprecated Source/Sink / DataContractModel authoring). Those samples are removed so they cannot be mistaken for ETLantic 0.18 APIs.

Prefer Polars tutorial and examples/portable_polars_kernel.py.

Authoritative surfaces: Capabilities, runnable Examples, and repository examples/.

Intent (historical)

This design study explored a polars pipeline workflow. Treat it as product research only. Do not implement from this page.
