reactive streams in java. a sequential program runs on a flat timeline. each task is only started after the previous one completes. in concurrent programs, multiple tasks may be running during the same time period and a new task may begin at any time. in threaded programs, introducing concurrency trades space for time. allocating memory for more threads allows application servers to make network requests concurrently instead of sequentially. threaded network requests can dramatically reduce server response times, but like all trade-offs this approach has its limits. unchecked thread creation can cause a server to run out of memory or to spend too much time to context switching. thread pools can help manage these problems, but under heavy load the number of threads in an application server’s pool will eventually be exhausted. when this happens network requests will be serialized, causing response times to rise. at this point the only way to bring down response times again is to scale up more servers, which increases costs. reactive programming allows concurrent network requests to be made without threads. instead of creating a thread which immediately blocks on io, a callback is asynchronously invoked when data is received from the stream. this dramatically increases the number of
