The article discusses the challenges of using Java's virtual threads in web development, particularly regarding memory management and concurrency. It highlights the risks of memory bloat when developers do not implement adequate flow control mechanisms. With virtual threads simplifying concurrency, it emphasizes a developer's responsibility to manage resources effectively, drawing comparisons to traditional threading and tools like Clojure's core.async. The comments further delve into the balance between performance and memory efficiency, with some users sharing their successful strategies for limiting concurrency using virtual threads without running into memory issues.
