## Rationale for this change Spark 4.1.2 is the latest maintenance release of the 4.1 line on Maven Central, containing bug fixes over 4.1.1. Keeping the Spark 4 dependency current picks up those fixes for the `vortex-spark_2.13` builds. Companion to #8812, which bumps the Spark 3 line. ## What changes are included in this PR? A one-line version bump in `java/gradle/libs.versions.toml`: `spark4 = "4.1.1"` → `spark4 = "4.1.2"`. No code changes. Verified locally against 4.1.2 with `:vortex-spark_2.13:test`: 120 tests ran, all passed except `VortexDataSourceS3MockTest`, which failed only because the local Docker daemon was not running (Testcontainers infrastructure requirement, unrelated to the Spark version). ## What APIs are changed? Are there any user-facing changes? None. Spark 4.1.2 is a drop-in maintenance upgrade; no connector code or public API is touched. Signed-off-by: jackylee <qcsd2011@gmail.com>

## Rationale for this change - Closes: #8807 Three benchmarks stayed flaky after #8742, flipping between the same two values on PRs that can't affect them. Same root causes and fixes as #8742: | Benchmark | Seen flaky on | Why | Fix | | --- | --- | --- | --- | | `true_count_vortex_buffer[128]` | ±11.17% on 9 unrelated PRs (#8805, #8811, #8812, #8820, #8843, #8803, …) | a 128-bit popcount measures harness overhead and code layout, not the count | drop the 128 size | | runend `compress[(100000, 4)]` | ±11.9% on #8805, #8750, #8856 | allocates in the timed region; glibc malloc differs across runner images | mimalloc as global allocator | | `cast_decimal` `copy_*[65536]` | identical flags on #8838 and #8724 | same glibc-malloc cause (512 KB alloc per iteration) | mimalloc as global allocator | Left alone: `compact_sliced[(4096, 90)]` (single sighting) and the CUDA walltime benches (hosted-runner walltime noise, a runner config issue). The allocator swap shifts every benchmark in the two touched binaries once — see the comment below. Needs a one-time CodSpeed acknowledgment, like #8742. ## What changes are included in this PR? One commit per benchmark; bench files only. Ran `cargo check` + `clippy` on the three bench targets, smoke-ran the binaries, `cargo +nightly fmt`. --------- Signed-off-by: Claude <noreply@anthropic.com> Co-authored-by: Claude <noreply@anthropic.com>

Rationale for this change
Spark 3.5.9 was released to Maven Central on 2026-07-12 as the latest maintenance
release of the 3.5 line, containing bug fixes over 3.5.8. Keeping the Spark 3
compileOnly/test dependency current picks up those fixes for the
vortex-sparkconnector's Spark 3 builds.
What changes are included in this PR?
A one-line version bump in
java/gradle/libs.versions.toml:spark3 = "3.5.8"→spark3 = "3.5.9". No code changes.Verified locally against 3.5.9 with
:vortex-spark_2.12:test: 120 tests ran, allpassed except
VortexDataSourceS3MockTest, which failed only because the local Dockerdaemon was not running (Testcontainers infrastructure requirement, unrelated to the
Spark version).
What APIs are changed? Are there any user-facing changes?
None. Spark 3.5.9 is a drop-in maintenance upgrade; no connector code or public API
is touched.
