> **Stacked PR series (6 parts) — splitting the Spark DataSource V2 connector.** > All six target `main`. They build on each other, so **review and merge in order** — until the earlier parts merge, this PR's diff includes their changes too. > > 1. Cargo workspace + `native-common` extraction > 2. `datafusion-spark-bridge` Rust SDK > 3. Spark connector Java SPI > **➤ 4.** Spark DataSource V2 connector (Scala) > 5. Bridge scaffold generator > 6. End-to-end examples ## Purpose The connector: a Spark **DataSource V2** implementation over the Java SPI and the bridge SDK. Covers DSv2 wiring (source/table/scan/builder), the per-partition columnar read path with Arrow→Spark conversion, V2 **predicate pushdown**, a **shared-scan mode** backed by a per-executor refcounted cache, and `SupportsReportPartitioning` for shuffle elision. These share the scan-mode model and scan builder, so they land as one unit. Includes the connector test suite and module README. 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
