Monix Task: Lazy, Async and Awesome
summary
Monix Task presents a lazy alternative to Scala Future that runs on JVM and Scala.js, ships as Monix 2.3, and interops with Cats. It models a Task as a thunk that returns a Future, provides lazy Future semantics with evalOnce/eval/defer/fork, a stack-safe flatMap, batching for throughput, a scheduler-driven timeout and backoff API, cancelable Future runAsync, memoize on success, parallel gather that cancels losers, a semaphore (example limit 16), a circuit breaker and MVar primitives.
