Hello,

Do you know how I can prevent a job to be run if one is already running?

// From Ktor
    get("/longtask") {
        call.respondText("OK")

        runLongTask(settings) // Returns a Job
    }

What I would like is, when /longtask is called for the first time, call the function runLongTask, but if it's called a second time, and runLongTask from the first call is not finished yet, to run it again. Not at all.

So do you want to run it the second time or not?

Not :)
