How to efficiently handle large JSON payloads in a Spring Boot REST API without running into memory issues?
Does anyone know how to I'm currently developing a Spring Boot REST API (version 2.5.6) that needs to process quite large JSON payloads, sometimes exceeding 10MB. When I try to handle these requests, I often run into `java.lang.OutOfMemoryError: Java heap space`. I've configured the server with `spring.servlet.multipart.max-file-size` and `spring.servlet.multipart.max-request-size` to 20MB in my application properties, but it doesn’t seem to help. Here's a snippet of how I'm currently parsing the request: ```java @PostMapping("/upload") public ResponseEntity<String> handleFileUpload(@RequestBody MyLargeDataObject data) { // Processing logic here return ResponseEntity.ok("Data processed successfully"); } ``` I also tried increasing the heap size with `-Xmx512m` when starting the application, which helped a bit, but I'm concerned that this isn't a sustainable solution. I've read about using `Streaming` and `ObjectMapper` for Jackson, but I'm not sure how to implement that here effectively. What are the best practices for efficiently handling such large payloads in a Spring Boot REST API while avoiding memory-related issues? Are there specific configurations or patterns I should consider? Any help would be greatly appreciated! This is part of a larger CLI tool I'm building. For context: I'm using Java on Linux.
