Death's Spring Batch course, this is truly the path of a real system executioner...☠️ If you thought Spring Batch was just another ordinary batch framework, you're gravely mistaken. kill-9's course doesn't give you theory—it gives you real weapons to survive in the bloody battlefield of actual combat. Flat files? Fixed-length? Complex log files? Instead of just saying "figure it out yourself," he explains everything sharp as a blade so you can actually use it in real work situations. Even when choosing a single delimiter, you'll understand "why it has to be done this way." Code, explanations, practice, execution commands... the entire course is filled with the mindset of "this is real combat." You're not just learning—you feel like you're becoming a 'batch terminator.' And the more you listen, the more confidence builds that someday you too will be able to leave a mark on systems with a single line of open source code. Batch prepared for death—are you still hesitating? The moment you take this course, you too become a true member of the 'kill-9 squad.' ☠️🔥
