Flatmap concurrency
WebSep 2, 2024 · This reactive operator has a concurrency level of 256 by default, meaning it executes at most 256 getUser calls simultaneously. This number is configurable via method parameter using an overloaded version of flatMap. It's worth noting, that since operations are happening in parallel, we don't know the resulting order. ... WebBy default, Cats Effect provides an instance of ContextShift [IO] that manages thread-pools, but only inside an implementation of IOApp . Custom instances of ContextShift [IO] can be created using an ExecutionContext: import cats.effect. { ContextShift, IO } import scala.concurrent.
