Spring REST Gigantomania: Handling Multi-Gigabyte POST Requests
summary
Covers implementing streaming processing of multi-gigabyte HTTP POST requests in Spring to handle cases where requests exceed available memory. Explains four concrete scenarios and techniques: sending large data over HTTP, receiving/streaming large HTTP payloads in Spring, writing streamed data into PostgreSQL, and reading large data from PostgreSQL — all aimed at bounded-memory, efficient resource usage.
