Batch processing, a paradigm born out of outdated technology constraints, is misaligned with how AI should function and stifles its capabilities. Generative AI thrives on real-time, contextual data, but traditional machine learning mirrors the batch-oriented thinking, resulting in rigid and inaccurate applications. The need for real-time, event-driven architectures arises from the inadequacy of batch systems to handle dynamic demands. Stream processing platforms provide continuous, low-latency data flows and real-time computation, enabling proactive AI systems that can react dynamically to changing inputs and operate autonomously. By integrating AI applications with stream processing platforms, we can move towards reactive to proactive AI systems, enable real-time personalization and decision-making, ensure LLMs operate on the freshest data, create scalable architectures, and bridge the gap between static systems of the past and dynamic AI-powered futures.
