Quartz StatefulJob / non-StatefulJob

Question

Would you please explain to me the exact mean of the StatefulJob in quartz and it's difference with none StatefulJob?

Answer 1

StatefulJob interface, provides 2 things,

first: only one job will be run any time

second: in (SimpleTriggerBean) you will not worry about your job running duration. it means that the next run will be done after delay time after ending of previous one.
