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.
