At first I was like, "Do I really need to know this?? Is it right for my career to study this??" But wow, this is really so beneficial. It's not just a simple lecture - you learn about the service called Flink, but it seems like a lecture that lets you see beyond that.

I really enjoyed the lecture.

Most developers are still stuck on Batch and CronJobs when it comes to data processing. However, in real-world production environments, data is generated continuously, and failing to process that flow immediately leads to latency, bottlenecks, and consistency issues. Having personally dealt with real-time recommendations, state synchronization, and event delay problems in high-traffic environments, I’ve often asked myself, "Is batch processing really the right approach for this?" This course begins with that very question. It explores how to use Apache Flink to perform computations the moment data flows, manage state securely, and produce accurate results based on Event Time—all from a practical perspective. Beyond simple theoretical explanations, you will experience how real-time stream processing systems are designed and operated through actual source code and architectures. For those who found real-time processing vague or were curious about the world beyond messaging, this course will provide a clear sense of direction.

Apache Flink, the real-time ultra-low latency platform used by Naver interviewers

Hello Boosta!! It's a difficult platform, but I tried my best to explain and share things as simply as possible. Thank you for your encouraging review!!

ほとんどの開発者は、データ処理について語る際、依然としてバッチ（Batch）やCronJobにとどまっています。しかし、実際のサービス環境ではデータが絶え間なく生成されており、その流れを即座に処理できなければ、遅延・ボトルネック・整合性の問題へとつながります。私自身も大規模なトラフィック環境で、リアルタイム推薦、状態同期、イベント遅延といった問題に直面し、「これをバッチで処理するのが正解なのだろうか？」と何度も悩みました。この講義は、まさにその問いから始まります。Apache Flinkを活用し、データが流れる瞬間に演算を行い、状態を安全に管理し、Event Timeに基づいて正確な結果を導き出す方法を、実務の観点から紐解いていきます。単なる理論の説明ではなく、実際のソースコードや構造を通じて、リアルタイム・ストリーム処理システムがどのように設計・運用されているかを体験できます。リアルタイム処理が漠然としていた方、メッセージングのその先の領域が気になっていた方にとって、この講義は明確な指針となるはずです。
