ML Pipeline Workflow

Complete end-to-end MLOps pipeline orchestration from data preparation through model deployment.

Do not use this skill when

• The task is unrelated to ml pipeline workflow
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Overview

This skill provides comprehensive guidance for building production ML pipelines that handle the full lifecycle: data ingestion → preparation → training → validation → deployment → monitoring.

Use this skill when

• Building new ML pipelines from scratch
• Designing workflow orchestration for ML systems
• Implementing data → model → deployment automation
• Setting up reproducible training workflows
• Creating DAG-based ML orchestration
• Integrating ML components into production systems

• model-training.md - Training workflows and best practices
• model-validation.md - Validation strategies and metrics
• model-deployment.md - Deployment patterns and serving architectures

Usage Patterns

Basic Pipeline Setup

# 1. Define pipeline stages
stages = [
    "data_ingestion",
    "data_validation",
    "feature_engineering",
    "model_training",
    "model_validation",
    "model_deployment"
]

# 2. Configure dependencies
# See assets/pipeline-dag.yaml.template for full example

Production Workflow

1. Data Preparation Phase

   • Ingest raw data from sources
   • Run data quality checks
   • Apply feature transformations
   • Version processed datasets

2. Training Phase

   • Load versioned training data
   • Execute training jobs
   • Track experiments and metrics
   • Save trained models

3. Validation Phase

   • Run validation test suite
   • Compare against baseline
   • Generate performance reports
   • Approve for deployment

4. Deployment Phase

   • Package model artifacts
   • Deploy to serving infrastructure
   • Configure monitoring
   • Validate production traffic

Best Practices

Pipeline Design

• Modularity: Each stage should be independently testable
• Idempotency: Re-running stages should be safe
• Observability: Log metrics at every stage
• Versioning: Track data, code, and model versions
• Failure Handling: Implement retry logic and alerting

Data Management

• Use data validation libraries (Great Expectations, TFX)
• Version datasets with DVC or similar tools
• Document feature engineering transformations
• Maintain data lineage tracking

Model Operations

• Separate training and serving infrastructure
• Use model registries (MLflow, Weights & Biases)
• Implement gradual rollouts for new models
• Monitor model performance drift
• Maintain rollback capabilities

Deployment Strategies

• Start with shadow deployments
• Use canary releases for validation
• Implement A/B testing infrastructure
• Set up automated rollback triggers
• Monitor latency and throughput

Integration Points

Orchestration Tools

• Apache Airflow: DAG-based workflow orchestration
• Dagster: Asset-based pipeline orchestration
• Kubeflow Pipelines: Kubernetes-native ML workflows
• Prefect: Modern dataflow automation

Experiment Tracking

• MLflow for experiment tracking and model regi
