Amogh-2404 opened a new pull request, #195: URL: https://github.com/apache/datafusion-site/pull/195
This adds a tutorial blog post on the Arrow C Data Interface, using DataFusion Comet's real Rust↔JVM handoff as the worked example. It addresses apache/datafusion-comet#3678. Closes apache/datafusion-comet#3678 - New post: `content/blog/2026-06-06-arrow-c-data-interface.md` - 5 diagrams under `content/images/arrow-c-data-interface/` - Category: tutorial The post separates the two questions the interface answers — memory layout vs. ownership — and traces a single `Int32` column `[1, 2, NULL, 4]` field by field across the boundary. The Comet section (`move_to_spark`, `from_spark`, `executePlan`, `CometPlainVector`, the `arrow_ffi_safe` copy fallbacks) is pinned to source at a fixed commit (`e79183ee`). Happy to adjust scope, framing, or length before merge — flag anything you'd like covered or cut. -- This is an automated message from the Apache Git Service.
