Spring Boot: Handling a REST Endpoint That Queries More Data Than Memory Available
Introduction
Handling large data sets efficiently is a common challenge in modern web applications, especially when dealing with REST endpoints in Spring Boot. If not managed properly, querying more data than the available memory can lead to performance degradation and application crashes. This article explores various techniques to handle large data sets, providing detailed code examples in Java to illustrate each method.
Understanding the Problem
Memory limitations in Java applications can cause significant issues when attempting to load large data sets. When a REST endpoint queries more data than the available memory can handle, it can result in OutOfMemoryErrors and negatively impact application performance. Understanding these limitations is crucial for designing efficient data-handling strategies.

Pagination
Explanation and Benefits Pagination is a technique that divides a large data set into smaller chunks or pages, allowing the application to load and process only a subset of the data at a time. This reduces memory usage and improves performance.
