Hi Lan, Thank you. In option 1: Do you mean using *etaMillis of **TaskOptions *using to specify the execute time? This could be a solution. We can trigger a TaskInit by cron and create 48 tasks in queue(every 30 minutes) to avoid chain task.
In option 2: This is my first thought about cron.xml . I just wish a simple syntax to support such requirement. If I change the schedule from 30 minutes to 2 minutes, the cron.xml will be 1800 entries.
