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.
