BenchBox v0.1.2: release summary

BenchBox v0.1.2 was released on February 14, 2026.

This post is a summary of what changed in this version, including a shift to ASCII visualizations.

TL;DR

• Charts are now terminal-native ASCII by default; Plotly HTML export is removed.
• DataFrame mode now covers major suites including TPC-H, TPC-DS, SSB, ClickBench, NYC Taxi, and TSBS DevOps, plus more DataFrame engines.
• SQL platform and table-format support expanded significantly.
• Query plan analysis, tuning, and comparison workflows are more integrated.
• Reliability improved across TPC-DS generation, cloud adapters, and non-interactive CLI runs.

At a glance

What changed for typical workflows

1. Visualization and reporting

Before: chart generation often produced HTML artifacts that were useful in browser-centric workflows.

Now: chart output is optimized for text-first workflows.

• Inline ASCII charts are shown in terminal output and tool responses.
• The default experience is no longer dependent on optional visualization extras.
• This is especially useful for MCP/agent use, where inline content is easier to consume than file paths.

2. SQL and DataFrame usage

DataFrame mode is no longer a narrow path. v0.1.2 extends DataFrame query implementations across TPC-H, TPC-DS, SSB, ClickBench, NYC Taxi, and TSBS DevOps, plus additional BenchBox suites.

Practical impact:

• Teams can evaluate SQL and DataFrame execution styles within one framework.
• Comparative workflows (same benchmark, different mode/platform) are easier to run consistently.
• The release prioritizes breadth, but validation and consistency checks remain critical as coverage grows.

3. Platform and format breadth

v0.1.2 adds significant SQL platform coverage and broadens open table format support.

Practical impact:

• More teams can run BenchBox against their existing stack without custom adapters.
• Format-level benchmarking scenarios are easier to model and compare.
• Cross-platform analysis becomes more useful because platform diversity increased.

Major additions

DataFrame mode expansion

v0.1.2 expands DataFrame implementations across the core benchmark groups, including:

• TPC-H
• TPC-DS
• SSB
• ClickBench
• NYC Taxi
• TSBS DevOps
• Other BenchBox benchmark suites

Supported DataFrame engines in the release include Polars, DuckDB DataFrame paths, DataFusion, PySpark, Pandas, Modin, Dask, and cuDF.

ASCII visualization as default

Key properties of the new default charting path:

• Inline rendering for CLI and MCP responses
• ANSI + Unicode terminal output with fallback behavior
• Focus on benchmark-friendly summaries and comparisons

Trade-off to note:

• Plotly HTML/PNG/SVG workflow is no longer the built-in default path.

SQL adapter expansion

v0.1.2 adds many platform adapters and improves managed/cloud coverage, including PostgreSQL, Trino/Presto families, Spark variants, Athena, Synapse/Fabric paths, and other warehouse engines documented in the changelog.

Notable additions called out in the v0.1.2 changelog:

• PostgreSQL
• Trino and PrestoDB
• Apache Spark and managed Spark variants
• AWS Athena
• Azure Synapse and Microsoft Fabric
• Firebolt and MotherDuck

Query-plan and comparison tooling

v0.1.2 improves plan capture and cross-run comparison workflows, including parser coverage and regression detection paths.

Practical impact:

• Easier to tie performance changes to execution plan differences.
• Better support for “run, compare, explain” loops during optimization work.

Major fixes and stability work

v0.1.2 includes substantial reliability improvements that are easy to miss if you only scan feature headlines.

TPC-DS generation and load reliability

• Fixes for fractional scale-factor generation edge cases
• Improvements around streaming compression/chunk handling
• Reduced failure modes in data generation and load flows

Cloud and adapter stability

• Credential refresh and setup-ordering fixes
• Path/key handling fixes for storage-backed workflows
• Adapter-specific correctness and robustness improvements

CLI and quality improvements

• Non-interactive mode behavior fixes
• --quiet propagation and output behavior improvements
• Broad type-safety cleanup across production paths

Changed behavior to be aware of

• Plotly-based chart output is removed in favor of ASCII-first rendering.
• Some visualization expectations from older runs/docs may no longer match v0.1.2 defaults.
• If you depended on browser-native chart artifacts, plan a separate export/visualization path.

Quick upgrade checks

After upgrading to v0.1.2:

1. Confirm installed version:

benchbox --version

2. Run a smoke benchmark with non-interactive settings:

benchbox run --platform duckdb --benchmark tpch --scale 0.01 --phases power --non-interactive

3. Validate chart behavior in your environment:

benchbox visualize benchmark_runs/results/<result_file>.json

4. If your team uses DataFrame mode, run one benchmark in SQL mode and one in DataFrame mode to confirm expected parity and runtime characteristics.

Bottom line

v0.1.2 is a large release focused on practical usability:

• better default output for terminal-centric workflows,
• broader benchmark/platform coverage,
• and stronger reliability for repeated benchmark operations.

For teams already using BenchBox, this version is mainly about faster feedback loops with less friction.
