LuciferYang opened a new pull request, #12524: URL: https://github.com/apache/gluten/pull/12524
### What changes were proposed in this pull request? The `<delta.binary.version>20</delta.binary.version>` property lived only in the `spark-3.2` Maven profile, which was removed by #11351. Since then, `src-delta20/` under both `backends-clickhouse/` and `gluten-delta/` has been unreachable dead code: - No profile currently sets `delta.binary.version=20` (`spark-3.3` → 23, `spark-3.4` → 24, `spark-3.5` → 33, `spark-4.0` / `spark-4.1` → 40). - No CI job, doc, or script activates the directories. - Every deleted class has a live replacement in `src-delta23/` and `src-delta33/` (and, for `gluten-delta`, `src-delta24/` / `src-delta40/` as well), so no user-visible symbol is lost. This PR deletes 28 files, 6499 LOC: - `backends-clickhouse/src-delta20/` (25 files) - `gluten-delta/src-delta20/` (3 files) ### How was this patch tested? Verified with a clean rebuild on `spark-3.3` + `backends-clickhouse` + `delta` profile (the minimum supported Spark version). Baseline `upstream/main` builds green pre-deletion; post-deletion also builds green. -- This is an automated message from the Apache Git Service.
