## Which issue does this PR close? - Validates apache/arrow-rs#12208. ## Rationale for this change Measure whether trimming unreferenced dictionary value suffixes improves DataFusion queries when IPC spill is forced under low memory. ## What changes are included in this PR? The first commit pins Arrow to #12208 parent `b2b7d470`; the tip pins Arrow to the exact PR head `69e96594`. There are no DataFusion runtime changes. ## What is the testing strategy for this PR? Run hosted TPC-H, TPC-DS, and partitioned ClickBench benchmarks with RLE dictionary reads enabled and suite-specific low memory limits that force spilling. The benchmark bot compares the two commits directly. The exact tip passed `cargo check -p datafusion`. The full pre-push clippy hook also exposed a test-only unused import on both the parent and tip pins; this is unrelated to the Arrow change. ## Are there any user-facing changes? No. This PR is benchmark-only and must not be merged. ## AI usage disclosure Codex helped prepare and validate the dependency pins and hosted benchmark configuration. -- This is an automated message from the Apache Git Service.
