-scripts/dataset_manager.py - Dataset creation and management
-scripts/sql_manager.py - SQL-based dataset querying and transformation

Prerequisites

-uv package manager installed
-HF_TOKEN environment variable must be set with a Write-access token

---

Query, transform, and push Hugging Face datasets using DuckDB SQL. The hf:// protocol provides direct access to any public dataset (or private with token).

Quick Start

bash

# Query a dataset
uv run scripts/sql_manager.py query \
  --dataset "cais/mmlu" \
  --sql "SELECT * FROM data WHERE subject='nutrition' LIMIT 10"

# Get dataset schema
uv run scripts/sql_manager.py describe --dataset "cais/mmlu"

# Sample random rows
uv run scripts/sql_manager.py sample --dataset "cais/mmlu" --n 5

# Count rows with filter
uv run scripts/sql_manager.py count --dataset "cais/mmlu" --where "subject='nutrition'"

SQL Query Syntax

Use data as the table name in your SQL - it gets replaced with the actual hf:// path:

sql

-- Basic select
SELECT * FROM data LIMIT 10

-- Filtering
SELECT * FROM data WHERE subject='nutrition'

-- Aggregations
SELECT subject, COUNT(*) as cnt FROM data GROUP BY subject ORDER BY cnt DESC

-- Column selection and transformation
SELECT question, choices[answer] AS correct_answer FROM data

-- Regex matching
SELECT * FROM data WHERE regexp_matches(question, 'nutrition|diet')

-- String functions
SELECT regexp_replace(question, '\n', '') AS cleaned FROM data

Common Operations

1. Explore Dataset Structure

bash

# Get schema
uv run scripts/sql_manager.py describe --dataset "cais/mmlu"

# Get unique values in column
uv run scripts/sql_manager.py unique --dataset "cais/mmlu" --column "subject"

# Get value distribution
uv run scripts/sql_manager.py histogram --dataset "cais/mmlu" --column "subject" --bins 20

2. Filter and Transform

bash

# Complex filtering with SQL
uv run scripts/sql_manager.py query \
  --dataset "cais/mmlu" \
  --sql "SELECT subject, COUNT(*) as cnt FROM data GROUP BY subject HAVING cnt > 100"

# Using transform command
uv run scripts/sql_manager.py transform \
  --dataset "cais/mmlu" \
  --select "subject, COUNT(*) as cnt" \
  --group-by "subject" \
  --order-by "cnt DESC" \
  --limit 10

3. Create Subsets and Push to Hub

bash

# Query and push to new dataset
uv run scripts/sql_manager.py query \
  --dataset "cais/mmlu" \
  --sql "SELECT * FROM data WHERE subject='nutrition'" \
  --push-to "username/mmlu-nutrition-subset" \
  --private

# Transform and push
uv run scripts/sql_manager.py transform \
  --dataset "ibm/duorc" \
  --config "ParaphraseRC" \
  --select "question, answers" \
  --where "LENGTH(question) > 50" \
  --push-to "username/duorc-long-questions"

4. Export to Local Files

bash

# Export to Parquet
uv run scripts/sql_manager.py export \
  --dataset "cais/mmlu" \
  --sql "SELECT * FROM data WHERE subject='nutrition'" \
  --output "nutrition.parquet" \
  --format parquet

# Export to JSONL
uv run scripts/sql_manager.py export \
  --dataset "cais/mmlu" \
  --sql "SELECT * FROM data LIMIT 100" \
  --output "sample.jsonl" \
  --format jsonl

5. Working with Dataset Configs/Splits

bash

# Specify config (subset)
uv run scripts/sql_manager.py query \
  --dataset "ibm/duorc" \
  --config "ParaphraseRC" \
  --sql "SELECT * FROM data LIMIT 5"

# Specify split
uv run scripts/sql_manager.py query \
  --dataset "cais/mmlu" \
  --split "test" \
  --sql "SELECT COUNT(*) FROM data"

# Query all splits
uv run scripts/sql_manager.py query \
  --dataset "cais/mmlu" \
  --split "*" \
  --sql "SELECT * FROM data LIMIT 10"

6. Raw SQL with Full Paths

For complex queries or joining datasets:

bash

uv run scripts/sql_manager.py raw --sql "
  SELECT a.*, b.* 
  FROM 'hf://datasets/dataset1@~parquet/default/train/*.parquet' a
  JOIN 'hf://datasets/dataset2@~parquet/default/train/*.parquet' b
  ON a.id = b.id
  LIMIT 100
"

Python API Usage

python

from sql_manager import HFDatasetSQL

sql = HFDatasetSQL()

# Query
results = sql.query("cais/mmlu", "SELECT * FROM data WHERE subject='nutrition' LIMIT 10")

# Get schema
schema = sql.describe("cais/mmlu")

# Sample
samples = sql.sample("cais/mmlu", n=5, seed=42)

# Count
count = sql.count("cais/mmlu", where="subject='nutrition'")

# Histogram
dist = sql.histogram("cais/mmlu", "subject")

# Filter and transform
results = sql.filter_and_transform(
    "cais/mmlu",
    select="subject, COUNT(*) as cnt",
    group_by="subject",
    order_by="cnt DESC",
    limit=10
)

# Push to Hub
url = sql.push_to_hub(
    "cais/mmlu",
    "username/nutrition-subset",
    sql="SELECT * FROM data WHERE subject='nutrition'",
    private=True
)

# Export locally
sql.export_to_parquet("cais/mmlu", "output.parquet", sql="SELECT * FROM data LIMIT 100")

sql.close()

HF Path Format

DuckDB uses the hf:// protocol to access datasets:

code

hf://datasets/{dataset_id}@{revision}/{config}/{split}/*.parquet

Examples:

-hf://datasets/cais/mmlu@~parquet/default/train/*.parquet
-hf://datasets/ibm/duorc@~parquet/ParaphraseRC/test/*.parquet

The @~parquet revision provides auto-converted Parquet files for any dataset format.

Useful DuckDB SQL Functions

sql

-- String functions
LENGTH(column)                    -- String length
regexp_replace(col, '\n', '')     -- Regex replace
regexp_matches(col, 'pattern')    -- Regex match
LOWER(col), UPPER(col)           -- Case conversion

-- Array functions  
choices[0]                        -- Array indexing (0-based)
array_length(choices)             -- Array length
unnest(choices)                   -- Expand array to rows

-- Aggregations
COUNT(*), SUM(col), AVG(col)
GROUP BY col HAVING condition

-- Sampling
USING SAMPLE 10                   -- Random sample
USING SAMPLE 10 (RESERVOIR, 42)   -- Reproducible sample

-- Window functions
ROW_NUMBER() OVER (PARTITION BY col ORDER BY col2)

Example 1: Create Training Subset from Existing Dataset

bash

# 1. Explore the source dataset
uv run scripts/sql_manager.py describe --dataset "cais/mmlu"
uv run scripts/sql_manager.py histogram --dataset "cais/mmlu" --column "subject"

# 2. Query and create subset
uv run scripts/sql_manager.py query \
  --dataset "cais/mmlu" \
  --sql "SELECT * FROM data WHERE subject IN ('nutrition', 'anatomy', 'clinical_knowledge')" \
  --push-to "username/mmlu-medical-subset" \
  --private

Example 2: Transform and Reshape Data

bash

# Transform MMLU to QA format with correct answers extracted
uv run scripts/sql_manager.py query \
  --dataset "cais/mmlu" \
  --sql "SELECT question, choices[answer] as correct_answer, subject FROM data" \
  --push-to "username/mmlu-qa-format"

Example 3: Merge Multiple Dataset Splits

bash

# Export multiple splits and combine
uv run scripts/sql_manager.py export \
  --dataset "cais/mmlu" \
  --split "*" \
  --output "mmlu_all.parquet"

Example 4: Quality Filtering

bash

# Filter for high-quality examples
uv run scripts/sql_manager.py query \
  --dataset "squad" \
  --sql "SELECT * FROM data WHERE LENGTH(context) > 500 AND LENGTH(question) > 20" \
  --push-to "username/squad-filtered"

Example 5: Create Custom Training Dataset

bash

# 1. Query source data
uv run scripts/sql_manager.py export \
  --dataset "cais/mmlu" \
  --sql "SELECT question, subject FROM data WHERE subject='nutrition'" \
  --output "nutrition_source.jsonl" \
  --format jsonl

# 2. Process with your pipeline (add answers, format, etc.)

# 3. Push processed data
uv run scripts/dataset_manager.py init --repo_id "username/nutrition-training"
uv run scripts/dataset_manager.py add_rows \
  --repo_id "username/nutrition-training" \
  --template qa \
  --rows_json "$(cat processed_data.json)"
