Not Kotlin, but look into Webflux.

You might want to take a look into #coroutines and
launch
as well as Spring WebFlux

Thanks
Looking into webflux

You should also take a look into kotlinx-coroutines-reactive: https://github.com/Kotlin/kotlinx.coroutines/tree/master/reactive/kotlinx-coroutines-reactive With its extensions, you can easily use Webflux in the kotlin coroutines world: example usage:
Copy code
fun sampleApiCallThatReturnsMono(): Mono<ApiResponse> {
        ...
    }

    suspend fun webClientWithCoroutineExtension(): ApiResponse =
        client.[...].retrieve().awaitBody()

    suspend fun parallelCalls() = coroutineScope {
        val call1 = async { sampleApiCallThatReturnsMono().awaitSingle() }
        val call2 = async { webClientWithCoroutineExtension() }
        println("Call 1 result: ${call1.await()}, Call 2 result: ${call2.await()}")
    }

    suspend fun multipleFireAndForgetCalls() = coroutineScope { 
        repeat(10) {
            launch { webClientWithCoroutineExtension() }
        }
    }
