Inter-Reactive Kotlin Applications
summary
Claims that Eclipse Vert.x plus Kotlin coroutines let you write asynchronous, event-driven code in a sequential style, using awaitResult and a Vert.x dispatcher to run suspending functions on the right event loop. Demonstrates a nonblocking JSON streaming parser built with coroutine producers and channels that prints incremental parse events (tested with netcat), propagates cooperative backpressure between readStream/writeStream, and benchmarks showing a single-chunk vs ten-suspend case where coroutine performance stays comparable to the synchronous parser.
