Advanced Data Retrieval Techniques for Peak Performance
Key Points Prefetching is a powerful performance optimization technique that predicts and fetches data before explicit requests, making applications feel faster and more responsive. However, prefetching must be implemented with caution to avoid waste of resources. Memoization optimizes application performance by caching calculation results, thus avoiding redundant calculations. This strategy is especially effective for functions that always produce the same results for the same input. Concurrent data fetching, that is, obtaining multiple sets of data at the same time, can significantly improve the data retrieval efficiency. It is especially useful when dealing with a variety of complex and independent datasets. Lazy loading
