Thank you --------- You're welcome.
In option 1: Do you mean using *etaMillis of **TaskOptions *using to specify the execute time? ----------------------------------------------------------------------------------------------- Yes. We can trigger a TaskInit by cron and create 48 tasks in queue(every 30 minutes) to avoid chain task. ----------------------------------------------------------------------------------------------------- Good idea: I didn't think of that. I just wish a simple syntax to support such requirement ------------------------------------------------------- Me too.
