I have the next CronExpression in Siddhi (wso2 DAS):
define trigger periodicalTriggerStream at '0 0/15 * * * ?';
This expression is runing without problems, run every 15 mins
15, 30, 45 ....
I need that my trigger run when I start SIDDHI.
0, 15, 30, 45
Is posible combine two expressions?:
define trigger periodicalTriggerStream at '0 0/15 * * * ?';
define trigger periodicalTriggerStream at 'start';
Event triggers will generate events on an event stream with name same as the event trigger, having only one attribute with name "triggered_time" and type long. Basically, once the trigger emits an event, it behaves similar to an event stream. Therefore, we can put both cron events, start events in to a event stream and use it.
define trigger cronTriggerStream at '0 0/15 * * * ?';
define trigger startTriggerStream at 'start';
from cronTriggerStream
insert into periodicalTriggerStream;
from startTriggerStream
insert into periodicalTriggerStream;
