Two Paths to Context: When GenAI Agents Need a Real-Time Context Engine like DeltaStream — and When They Don’t

Intelligent agents rely on context to perform tasks effectively, with two primary approaches to providing this context being the Real-Time Context Engine (RTCE) and Fetch-on-Demand methods. The RTCE, exemplified by DeltaStream, continuously ingests and fuses data from various sources into a live materialized view, offering immediate and consistent access to current information, which is crucial for high-velocity environments, multi-agent systems, and scenarios requiring strict consistency and auditability. In contrast, the Fetch-on-Demand approach retrieves data as needed, offering flexibility but often leading to issues in governance, security, and auditability due to its ad-hoc nature. While the RTCE is essential in settings where speed and real-time accuracy are paramount, such as fraud detection and real-time trading, Fetch-on-Demand remains suitable for less time-sensitive applications. The recommendation is a hybrid model that leverages the strengths of both approaches, using DeltaStream for real-time state maintenance and Fetch-on-Demand for secondary context enrichment, to ensure a comprehensive and current understanding for agents.
