🌐 Visit our website →

Baselinr is a modern, open-source data profiling and drift detection framework for SQL-based data warehouses. It automatically profiles datasets, stores metadata and statistics, and detects drift over time.

🚀 Features

• Automated Profiling: Profile tables with column-level metrics (count, null %, distinct values, mean, stddev, histograms, etc.)
• Drift Detection: Compare profiling runs to detect schema and statistical drift with configurable strategies
• Type-Specific Thresholds: Adjust drift sensitivity based on column data type (numeric, categorical, timestamp, boolean) to reduce false positives
• Intelligent Baseline Selection: Automatically selects optimal baseline method (last run, moving average, prior period, stable window) based on column characteristics
• Advanced Statistical Tests: Kolmogorov-Smirnov (KS) test, Population Stability Index (PSI), Chi-square, Entropy, and more for rigorous drift detection
• Expectation Learning: Automatically learns expected metric ranges from historical profiling data, including control limits, distributions, and categorical frequencies for proactive anomaly detection
• Anomaly Detection: Automatically detects outliers and seasonal anomalies using learned expectations with multiple detection methods (IQR, MAD, EWMA, trend/seasonality, regime shift)
• Event & Alert Hooks: Pluggable event system for real-time alerts and notifications on drift, schema changes, anomalies, and profiling lifecycle events
• Partition-Aware Profiling: Intelligent partition handling with strategies for latest, recent_n, or sample partitions
• Adaptive Sampling: Multiple sampling methods (random, stratified, top-k) for efficient profiling of large datasets
• Multi-Database Support: Works with PostgreSQL, Snowflake, SQLite, MySQL, BigQuery, and Redshift
• Schema Versioning & Migrations: Built-in schema version management with migration system for safe database schema evolution
• Metadata Querying: Powerful CLI and API for querying profiling runs, drift events, and table history
• Dagster Integration: Built-in orchestration support with Dagster assets and schedules
• Configuration-Driven: Simple YAML/JSON configuration for defining profiling targets

2. Preview What Will Be Profiled

baselinr plan --config config.yml

This shows you what tables will be profiled without actually running the profiler.

3. Run Profiling

baselinr profile --config config.yml

4. Detect Drift

After running profiling multiple times:

baselinr drift --config config.yml --dataset customers

5. Query Profiling Metadata

Query your profiling history and drift events:

# List recent profiling runs
baselinr query runs --config config.yml --limit 10

# Query drift events
baselinr query drift --config config.yml --table customers --days 7

# Get detailed run information
baselinr query run --config config.yml --run-id <run-id>

# View table profiling history
baselinr query table --config config.yml --table customers --days 30

6. Check System Status

Get a quick overview of recent runs and active drift:

# Show status dashboard
baselinr status --config config.yml

# Show only drift summary
baselinr status --config config.yml --drift-only

# Watch mode (auto-refresh)
baselinr status --config config.yml --watch

# JSON output for scripting
baselinr status --config config.yml --json

7. Start Dashboard UI

Launch the web dashboard to view profiling runs, drift alerts, and metrics:

# Start dashboard (foreground mode)
baselinr ui --config config.yml

# Custom ports
baselinr ui --config config.yml --port-backend 8080 --port-frontend 3001

# Localhost only
baselinr ui --config config.yml --host 127.0.0.1

Press Ctrl+C to stop the dashboard. See docs/schemas/UI_COMMAND.md for more details.

• data_type_inferred: Inferred data type from values (email, url, date, etc.)
• column_stability_score: Column presence stability (0.0 to 1.0)
• column_age_days: Days since column first appeared
• type_consistency_score: Type consistency across runs (0.0 to 1.0)

Numeric Columns

• min: Minimum value
• max: Maximum value
• mean: Average value
• stddev: Standard deviation
• histogram: Distribution histogram (optional)

String Columns

• min: Lexicographic minimum
• max: Lexicographic maximum

See docs/guides/PROFILING_ENRICHMENT.md for detailed documentation on enrichment features.

🧠 Expectation Learning

Baselinr can automatically learn expected metric ranges from historical profiling data, creating statistical models that help identify outliers without explicit thresholds.

Key Features

• Automatic Learning: Continuously learns expected values for metrics like mean, stddev, null_ratio, count, and unique_ratio
• Control Limits: Calculates lower and upper control limits using Shewhart (3-sigma) method or EWMA (Exponentially Weighted Moving Average)
• Distribution Detection: Automatically detects if metrics follow normal or empirical distributions
• Categorical Frequencies: Tracks expected frequency distributions for categorical columns
• Separate from Baselines: Learned expectations are stored separately from drift detection baselines, enabling proactive anomaly detection

How It Works

Expectation learning analyzes historical profiling data over a configurable window (default: 30 days) to compute:

• Expected mean, variance, and standard deviation
• Control limits for outlier detection (3-sigma or EWMA-based)
• Distribution parameters (normal vs empirical)
• Expected categorical value frequencies

These learned expectations are automatically updated after each profiling run, providing an evolving model of what "normal" looks like for your data.

Configuration

Enable expectation learning in your config.yml:

storage:
  enable_expectation_learning: true
  learning_window_days: 30      # Historical window in days
  min_samples: 5                 # Minimum runs required for learning
  ewma_lambda: 0.2              # EWMA smoothing parameter (0 < lambda <= 1)

Use Cases

• Proactive Monitoring: Identify anomalies before they cause drift
• Automated Alerting: Flag unexpected metric values automatically
• Trend Analysis: Understand normal ranges for your data over time
• Quality Assurance: Ensure metrics stay within expected operational ranges

See docs/guides/EXPECTATION_LEARNING.md for comprehensive documentation on expectation learning.

🔄 Dagster Integration

Baselinr can create Dagster assets dynamically from your configuration:

from baselinr.integrations.dagster import build_baselinr_definitions

defs = build_baselinr_definitions(
    config_path="config.yml",
    asset_prefix="baselinr",
    job_name="baselinr_profile_all",
    enable_sensor=True,  # optional
)

🐍 Python SDK

Baselinr provides a high-level Python SDK for programmatic access to all functionality.

Quick Start

from baselinr import BaselinrClient

# Initialize client
client = BaselinrClient(config_path="config.yml")

# Build execution plan
plan = client.plan()
print(f"Will profile {plan.total_tables} tables")

# Profile tables
results = client.profile()
for result in results:
    print(f"Profiled {result.dataset_name}: {len(result.columns)} columns")

# Detect drift
drift_report = client.detect_drift("customers")

🔍 Drift Detection

Baselinr provides multiple drift detection strategies and intelligent baseline selection:

Available Strategies

1. Absolute Threshold (default): Simple percentage-based thresholds

   • Low: 5% change
   • Medium: 15% change
   • High: 30% change

2. Standard Deviation: Statistical significance based on standard deviations

3. Statistical Tests (advanced): Multiple statistical tests for rigorous detection

   • Numeric columns: KS test, PSI, Z-score
   • Categorical columns: Chi-square, Entropy, Top-K stability
   • Automatically selects appropriate tests based on column type

Intelligent Baseline Selection

Baselinr automatically selects the optimal baseline for drift detection based on column characteristics:

• Auto Selection: Automatically chooses the best baseline method per column
  • High variance columns → Moving average (smooths noise)
  • Seasonal columns → Prior period (accounts for weekly/monthly patterns)
  • Stable columns → Last run (simplest baseline)
• Moving Average: Average of last N runs (configurable, default: 7)
• Prior Period: Same period last week/month (handles seasonality)
• Stable Window: Historical window with low drift (most reliable)
• Last Run: Simple comparison to previous run (default)

Thresholds and baseline selection are fully configurable via the drift_detection configuration. See docs/guides/DRIFT_DETECTION.md for general drift detection and docs/guides/STATISTICAL_DRIFT_DETECTION.md for statistical tests.

🔔 Event & Alert Hooks

Baselinr includes a pluggable event system that emits events for drift detection, schema changes, and profiling lifecycle events. You can register hooks to process these events for logging, persistence, or alerting.

Built-in Hooks

• LoggingAlertHook: Log events to stdout
• SQLEventHook: Persist events to any SQL database
• SnowflakeEventHook: Persist events to Snowflake with VARIANT support

Example Configuration

hooks:
  enabled: true
  hooks:
    # Log all events
    - type: logging
      log_level: INFO
    
    # Persist to database
    - type: sql
      table_name: baselinr_events
      connection:
        type: postgres
        host: localhost
        database: monitoring
        username: user
        password: pass

Event Types

• DataDriftDetected: Emitted when drift is detected
• SchemaChangeDetected: Emitted when schema changes
• ProfilingStarted: Emitted when profiling begins
• ProfilingCompleted: Emitted when profiling completes
• ProfilingFailed: Emitted when profiling fails

Custom Hooks

Create custom hooks by implementing the AlertHook protocol:

from baselinr.events import BaseEvent

class MyCustomHook:
    def handle_event(self, event: BaseEvent) -> None:
        # Process the event
        print(f"Event: {event.event_type}")

Configure custom hooks:

hooks:
  enabled: true
  hooks:
    - type: custom
      module: my_hooks
      class_name: MyCustomHook
      params:
        webhook_url: https://api.example.com/alerts

See docs/architecture/EVENTS_AND_HOOKS.md for comprehensive documentation and examples.

🔄 Schema Versioning & Migrations

Baselinr includes a built-in schema versioning system to manage database schema evolution safely.

Migration Commands

# Check current schema version status
baselinr migrate status --config config.yml

# Apply migrations to a specific version
baselinr migrate apply --config config.yml --target 1

# Preview migrations (dry run)
baselinr migrate apply --config config.yml --target 1 --dry-run

# Validate schema integrity
baselinr migrate validate --config config.yml

How It Works

• Schema versions are tracked in the baselinr_schema_version table
• Migrations are applied incrementally and can be rolled back
• The system automatically detects when your database schema is out of date
• Migrations are idempotent and safe to run multiple times

🔍 Metadata Querying

Baselinr provides powerful querying capabilities to explore your profiling history and drift events.

Query Commands

# Query profiling runs with filters
baselinr query runs --config config.yml \
  --table customers \
  --status completed \
  --days 30 \
  --limit 20 \
  --format table

# Query drift events
baselinr query drift --config config.yml \
  --table customers \
  --severity high \
  --days 7 \
  --format json

# Get detailed information about a specific run
baselinr query run --config config.yml \
  --run-id abc123-def456 \
  --format json

# View table profiling history over time
baselinr query table --config config.yml \
  --table customers \
  --schema public \
  --days 90 \
  --format csv \
  --output history.csv
