First of all, I wanted to gather some information one how a simple event driven architecture works in real life. If this question is not suitable in here. please kindly let me know where I can ask these kind of questions.
Here is my usecase: My company has two department, Department A provides the data in HDFS to Department B, starts the process and generate final report. Schedule example Department A starts the process at 11:00 AM Department B starts the process at 05:00 PM
My questions is, How department B can starts the process as soon as data available from Department A.
My initial though is to have a periodic data availability checks on department B
