## Description
The Materialized View pattern generates prepopulated views over the data in one or more data stores when the data is poorly formatted for required query operations. These views are precomputed and stored, enabling fast query performance on data that would otherwise be expensive to query.


## Use Cases
Use when query performance is critical and data is not optimally structured for queries or when you need to precompute complex query results.





## Trade-offs


### Advantages

- Improved query performance

- Precomputed complex results

- Reduced query load on source data

- Optimized for read-heavy workloads




### Considerations & Drawbacks

- Data staleness

- Maintenance overhead

- Additional storage requirements
