How-to Guides¶

How-to guides are problem-oriented recipes that help you solve specific tasks with Duckalog. Each guide provides step-by-step solutions to real-world problems.

What are How-to Guides?¶

How-to guides differ from tutorials in their focus and approach:

• Goal-oriented: Solve specific problems rather than teaching concepts
• Direct and practical: Step-by-step solutions without extensive explanation
• Standalone: Each guide solves a complete problem independently
• Assumes basic knowledge: You understand Duckalog fundamentals

Popular How-to Guides¶

Configuration and Setup¶

Environment Management¶

Set up and manage different environments (development, staging, production) with proper separation of concerns.

You'll learn: - Environment-specific configuration patterns - Secure credential management across environments - Deployment strategies for different contexts - Docker and Kubernetes integration

Common problems solved: - "How do I manage different database connections for dev vs prod?" - "How do I keep secrets out of my configuration files?" - "How do I deploy same config to multiple environments?"

Secrets Persistence¶

Configure and manage secrets persistence with proper security considerations for temporary and persistent storage.

You'll learn: - Differences between temporary and persistent secrets - Security implications of each approach - Configuration patterns for optimal secret management - Best practices for secure credential handling

Common problems solved: - "When should I use persistent vs temporary secrets?" - "How do I balance security and convenience?" - "What are the security risks of persistent secrets?" - "How do I migrate between temporary and persistent secrets?"

Migration from Manual SQL¶

Migrate existing manual SQL workflows to Duckalog configuration-driven approach.

You'll learn: - Converting existing CREATE VIEW statements to Duckalog config - Preserving business logic during migration - Incremental migration strategies - Validation and testing approaches

Common problems solved: - "How do I move from manual SQL files to Duckalog?" - "How do I ensure my migrated views produce the same results?" - "How do I migrate a large number of existing views?"

Performance and Optimization¶

Performance Tuning¶

Optimize Duckalog performance for your specific workload and data characteristics.

You'll learn: - Memory and threading configuration - Query optimization techniques - Caching strategies - Performance monitoring and debugging

Common problems solved: - "How do I make my queries run faster?" - "How do I handle large datasets efficiently?" - "How do I optimize memory usage?"

Development and Debugging¶

Debugging Build Failures¶

Diagnose and resolve common catalog build issues and errors.

You'll learn: - Systematic debugging approaches - Common error patterns and solutions - Using diagnostic tools effectively - Prevention strategies

Common problems solved: - "Why is my catalog build failing?" - "How do I fix SQL syntax errors in my views?" - "How do I resolve path and file access issues?"

How-to vs Tutorials vs Reference¶

Choosing the Right Guide¶

Start Here If You:¶

• Have a specific problem: "I need to set up production configs"
