Quick Start Guide

1. Plan Your Architecture

Start with database and schema design principles to establish a solid foundation for your data organization.

2. Design Your Tables

Follow table design fundamentals to create efficient table structures that support your application’s needs.

3. Choose Data Types

Review data types to select appropriate data types for your specific use cases and requirements.

4. Optimize Performance

Implement index design strategies and consider materialized views for complex analytical queries.

5. Handle Complex Data

Use JSONB for semi-structured data and foreign tables for external data integration.

Key Design Principles

Performance-First Approach

• Choose appropriate storage modes (row, columnar, hybrid) based on access patterns
• Design indexes strategically to support common query patterns
• Implement partitioning for large tables to improve query performance
• Use materialized views to accelerate complex analytical queries

Scalability and Flexibility

• Plan for growth with proper schema design and data organization
• Leverage JSONB for evolving data structures without schema changes
• Implement tiered storage strategies for cost-effective data lifecycle management
• Design for both transactional and analytical workloads where needed

Data Integration

• Use foreign tables to access external data without ETL processes
• Implement proper data type choices and constraints for data quality
• Plan schema evolution strategies to accommodate changing requirements
• Consider generated columns for derived data and computed values

Tools and Features

Tacnode provides powerful features to support advanced table design:

• Multiple Storage Modes: Row, columnar, and hybrid storage for different workload patterns
• Advanced Partitioning: Range, hash, and list partitioning strategies
• Rich Data Types: Including JSONB for semi-structured data
• Materialized Views: Both full and incremental refresh options
• Foreign Data Wrappers: Connect to S3, Glue, Iceberg, Delta Lake, and more
• Online Schema Changes: Modify table structures without downtime

Best Practices Summary

1. Start Simple: Begin with straightforward designs and evolve as requirements become clear
2. Document Decisions: Maintain clear documentation of design choices and their rationale
3. Monitor Performance: Regularly review query patterns and optimize accordingly
4. Plan for Growth: Consider future scalability in your initial design decisions
5. Test Thoroughly: Validate performance assumptions with realistic data volumes
