Answer / srinivas
If you run multiple jobs with single command than we will the sequencers.
For example in real time data will load like below
Source--->Staging---->dimensions---->fact
If we wish to load the data sequncial manner first we will create staging jobs after that dimensions and last fact.
To process these will create sequencers and will trigger based on dependency.
