Bas Geerdink explains why and how ING is becoming more and more data-driven, sharing use cases, architecture, and technology choices along the way.

Watermarks are a system for measuring progress and completeness in out-of-order streaming systems and are utilized to emit correct results in a timely manner. Given the trend toward out-of-order processing in existing streaming systems, watermarks are an increasingly important tool when designing streaming pipelines. Slava Chernyak explains watermarks and explores real-world applications.

Apache Flink is a full-featured streaming framework with high throughput, millisecond latency, strong consistency, support for out-of-order streams, and support for batch as a special case of streaming. Kostas Tzoumas gives an overview of Flink and its streaming-first philosophy, as well as the project roadmap and vision: fully unifying the worlds of batch and streaming analytics.
