Batch Processing vs Real-Time Stream Processing

The text explores the ongoing shift from batch ETL (Extract, Transform, Load) to real-time streaming ETL, comparing their methodologies, advantages, and disadvantages. Batch processing handles large volumes of data by processing it at scheduled intervals, offering cost-effectiveness and flexibility but suffering from latency and complexity issues. In contrast, real-time stream processing processes data continuously as it is generated, providing low latency and scalability but presenting challenges such as a steep learning curve and data management complexities. The discussion highlights various use cases for each approach, including historical analysis and data backups for batch processing, and real-time customer applications, fraud detection, and cybersecurity for streaming. Ultimately, the choice between batch and real-time processing depends on specific use cases and objectives, with advancements like Streamkap making real-time streaming more accessible and easier to implement.
