Optimizing Data Fetching with Concurrency Control Techniques

This chapter delves into strategies for handling data retrieval from APIs that provide information in pages or through cursors. It covers methods like sequential fetching with keys, using for loops for efficient data retrieval, and employing map functions to fetch multiple items concurrently. Additionally, it emphasizes the importance of concurrency control tools such as P map and P limit to manage promises effectively, ensuring optimal performance and preventing issues like DDoS attacks.
