Handling Different Access Patterns with Event Sourcing

In this episode, part III of IV, we dive into advanced access patterns for Event Sourcing systems. Building on our previous discussions about retrieving individual entities, we'll explore how to effectively implement read models using the CQRS pattern to satisfy complex querying requirements.

We'll cover:

• Why basic entity retrieval isn't enough for real-world applications
• Creating optimized read models (projections) from event streams
• The key components of a projection system: projectionist, ledger, projector, and projection
• How different business needs can be addressed with multiple specialized projections
• Tackling performance challenges with very long event streams
• Using snapshots to improve entity reconstruction performance
• Breaking down long streams for better manageability and storage optimization

Join us as we discuss practical solutions for implementing Event Sourcing in production systems while maintaining excellent performance and flexibility.
