Its Yield Duration was default 1 sec. > I expected GetFile onTrigger() to be called every 30 secs, but it was being > called every 1 sec most of the time. > GetFile will call context.yield() when it polls a directory and gets an empty > list in return. It appears that a yield will ignore the Run Schedule. Many > standard processors call context.yield() when they have no work to do. > I changed my scheduling strategy to CRON Driven with its run schedule every > 30 seconds, and the onTrigger() was called every 30 seconds, even after a > yield. So CRON Driven scheduling is working as expected after a yield. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
