As you can guess from the curriculum and total lecture time before purchasing the course, This is a good course to take with the feeling of lightly sketching in your head when you have no understanding of Spring Batch at all. I bought it with the intention of sketching because I didn't have enough physical time to learn Spring Batch in depth, and I really like it. However, I do not recommend it to those who have already used Spring Batch at least once or have prior knowledge equivalent to that.
