DeltaStream Fusion is a comprehensive Unified Analytics Platform designed to integrate streaming, real-time, and batch analytics into a single solution, significantly simplifying complex analytics workflows. Built originally around Apache Flink, the platform addresses the inefficiencies of managing separate analytics stacks by offering real-time data ingestion, processing, and querying capabilities, all in one place. By unifying these processes, DeltaStream Fusion reduces operational complexity, infrastructure costs, and data synchronization issues, while enhancing governance and compliance. As a cloud-native, serverless solution, it automatically selects the most suitable engine for specific tasks, such as Apache Flink for streaming, Apache Spark for batch processing, and ClickHouse for low-latency queries. The platform enables the creation of real-time materialized views for instant insights and supports various use cases like real-time fraud detection, predictive maintenance, and customer analytics. DeltaStream Fusion empowers data teams to iterate faster and gain deeper insights by shifting analytics from traditional batch-oriented systems to continuous streaming, thereby lowering infrastructure costs and accelerating access to insights.
