DuckDB 2.0 (v2.0-cyanoptera head)

[joseph-isaacs]

Summary

• Tracking Issue: Duckdb 2.0 #8628

Builds on #9141 (DuckDB 2.0 support), merged with the current develop and bumped to the latest DuckDB 2.0 release-branch commit. DuckDB has not tagged v2.0.0 yet, so this pins the head of v2.0-cyanoptera. #9141's commits are squashed into one commit, with Mikhail Kot as co-author, so that DCO passes.

Changes

• All changes from Duckdb 2.0 #9141.
• Merge of develop:
  • vortex-duckdb/src/convert/vector.rs: keeps both sides. Duckdb 2.0 #9141 zeroes invalid decimal slots, duckdb: i16 Decimal on duckdb side may fit in Vortex's i8 decimal buffer #10155 narrows small decimals into an i8 buffer, and the i8 path now zeroes invalid slots as well.
  • vortex-duckdb/src/convert/expr.rs: uses the imported vortex_ensure_eq! where the merge left an unimported vortex_ensure!.
• DEFAULT_DUCKDB_VERSION bumped from 561522aea03e400bd20adc64fcc63e78b8721f3f (2026-09-30) to 8588363bf15e090fcbbfe2a68ec98b10c6866cb1 (2026-10-15, v2.0-cyanoptera head). The old commit is an ancestor, 2,315 commits behind.
• cpp/table_filter.cpp: DynamicFilterData::lock is now an annotated_shared_mutex, so it is read under annotated_shared_lock, as DuckDB does.
• httpfs is now an out-of-tree DuckDB extension with vcpkg dependencies, and DuckDB refuses to build it without VCPKG_TOOLCHAIN_PATH:
  • scripts/duckdb-r2-prepare.sh: on Linux, bootstraps DuckDB's pinned vcpkg (make setup-vcpkg) and keeps httpfs. The macOS universal build drops httpfs (and the hand-built universal OpenSSL), since vcpkg can't produce universal binaries and the S3 test only runs on Linux.
  • vortex-duckdb/build.rs: when building DuckDB from source, links httpfs only if VCPKG_TOOLCHAIN_PATH is set.
• DuckDB SQL logic test expectations regenerated with --complete against 8588363b:
  • 83 EXPLAIN plan snapshots changed because of DuckDB optimizer changes. For example, avg is no longer rewritten to sum/count, and duplicate pushed-down scan filters are now deduplicated.
  • The number of Vortex scans (2,572) and FILTER nodes (525) is unchanged, and every scan filter is still pushed down.
  • TPC-DS q9's last bucket changed in the 16th significant digit (…512 → …511) on both Parquet and Vortex. DuckDB now sums the floats in a different order.

Testing

• Locally against DuckDB 8588363b: duckdb-bench tpch --formats parquet,vortex --opt scale-factor=0.1 -i 1 ran all 22 queries on both formats. All DuckDB SQL logic tests pass.
• In CI, everything passes, including SQL logic tests, DuckDB S3 tests (httpfs built with vcpkg) and DCO. The exception is CodSpeed, which flags benchmarks in crates this PR doesn't touch.
• action/bench-sql on eb261dbc: no suite showed a confirmed regression. Note that DuckDB's own Parquet reader also changes in this bump, so the Parquet control rows are not a stable baseline for the DuckDB attribution.

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

⚠️ 1 benchmark measured no execution time

Nothing ran under measurement, usually because the compiler removed the code under test. This result is not comparable, so it counts as unchanged.

Preventing compiler optimizations

• bench_compare_sliced_dict_primitive[(3333, 10000)]

⚠️ 18 benchmarks spent significant time in system calls

System calls cannot be consistently instrumented, so they are not included in the measure, which understates the real cost. Please switch to the Walltime instrument to accurately measure system calls.

CodSpeed Performance Analysis reports "1 benchmark regressed" on both 55df3f5 and 0caa032. I don't think this PR causes it: compared with develop, the PR only changes vortex-duckdb, vortex-sqllogictest and scripts/duckdb-r2-prepare.sh. None of the CodSpeed benchmark crates (vortex-array, encodings, vortex-python, vortex-spatial) are touched, and CodSpeed's summary itself warns the walltime numbers are inconsistent on hosted runners. No fix to port, and I can't re-run the CodSpeed app check from here.

Benchmarks: Random Access 📖

Commits: PR 55df3f55 vs base c128e993
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: +4.4%
Engines: random-access No clear signal (+4.4%, environment too noisy confidence)
Vortex (geomean): hot 0.997x ➖
Parquet (geomean): hot 0.956x ➖
Shifts: Parquet (control) -4.4% · Median polish -0.5%

How to read Verdict and Engines

• Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
• Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
• Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
• Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
• Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

Verdict: Likely improvement (medium confidence)
Attributed Vortex impact: -25.5%
Engines: DataFusion No clear signal (+3.5%, low confidence) · DuckDB Likely improvement (-46.4%, environment too noisy confidence)
Vortex (geomean): hot 0.854x ✅ · cold 0.852x ✅
Parquet (geomean): hot 1.147x ❌ · cold 1.097x ➖
Shifts: Parquet (control) +14.7% · Median polish +0.5%

How to read Verdict and Engines

• Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
• Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
• Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
• Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
• Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

Commits: PR eb261dbc vs base c087cd96
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -10.7%
Engines: DataFusion No clear signal (+0.2%, low confidence) · DuckDB No clear signal (-20.4%, environment too noisy confidence)
Vortex (geomean): hot 0.989x ➖ · cold 1.013x ➖
Parquet (geomean): hot 1.108x ❌ · cold 0.982x ➖
Shifts: Parquet (control) +10.8% · Median polish +0.6%

How to read Verdict and Engines

• Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
• Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
• Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
• Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
• Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

Commits: PR eb261dbc vs base c1a2ca12
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -7.2%
Engines: DataFusion No clear signal (-0.1%, low confidence) · DuckDB No clear signal (-13.8%, environment too noisy confidence)
Vortex (geomean): hot 1.043x ➖ · cold 1.022x ➖
Parquet (geomean): hot 1.124x ❌ · cold 1.086x ➖
Shifts: Parquet (control) +12.4% · Median polish +4.8%

How to read Verdict and Engines

• Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
• Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
• Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
• Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
• Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

Commits: PR eb261dbc vs base c1a2ca12
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: -7.7%
Engines: DataFusion No clear signal (+0.0%, low confidence) · DuckDB No clear signal (-14.9%, environment too noisy confidence)
Vortex (geomean): hot 0.936x ➖ · cold 0.924x ➖
Parquet (geomean): hot 1.014x ➖ · cold 1.021x ➖
Shifts: Parquet (control) +1.4% · Median polish +0.0%

How to read Verdict and Engines

• Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
• Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
• Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
• Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
• Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.

Commits: PR eb261dbc vs base c087cd96
Verdict: No clear signal (environment too noisy confidence)
Attributed Vortex impact: +9.5%
Engines: DataFusion No clear signal (-11.5%, environment too noisy confidence) · DuckDB No clear signal (+35.5%, environment too noisy confidence)
Vortex (geomean): hot 0.990x ➖ · cold 1.040x ➖
Parquet (geomean): hot 0.904x ➖ · cold 0.871x ➖
Shifts: Parquet (control) -9.6% · Median polish +2.8%

How to read Verdict and Engines

• Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
• Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
• Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
• Hot vs cold: Every measurement is run several times. The first run is reported as the cold run, and the median of the runs after it is reported as the hot run. The verdict and significance use hot runs; each target's geomean reports hot and cold beside each other where the individual runs were recorded and hot alone where they were not, the cold column shows first-run cost per row, and hot/cold is how much of each run the warm path saves. Rows whose results predate per-run reporting show only one value, taken from the value the runner reported.
• Table cells: Each cell reads PR / base / %diff. The hot and cold columns mark a change as 🔴 slower or 🟢 faster once it clears this suite's threshold; anything smaller is noise here and is left unmarked, as is hot/cold, because a shift in the warm-up ratio is not a win or a loss by itself.
