Functions

func RunAsyncRunner

func RunAsyncRunner(ctx context.Context, tasksrv string, tasks chan task.Request, rnr *Runner)

RunAsyncRunner pulls tasks off a queue and processes them

func RunTask

func RunTask(tasks chan task.Request, ctx context.Context, cfg *task.Config) (drivers.RunResult, error)

RunTask helps sending a task.Request into the common concurrency stream. Refer to StartWorkers() to understand what this is about.

func StartWorkers

func StartWorkers(ctx context.Context, rnr *Runner, tasks <-chan task.Request)

StartWorkers operates the common concurrency stream, ie, it will process all IronFunctions tasks, either sync or async. In the process, it also dispatches the workload to either regular or hot functions.
