Tech Talk: Streaming in the World of Legacy Applications

There are common themes when people describe their reasons for rearchitecting legacy business applications, at a technical level: Speed & Scalability. At a business level: The need to gain new real-time insights. These legacy applications commonly center around some central datastore such as a relational database. Moving away from this architecture requires massive migration effort. The costs and risks associated with such an effort can sometimes be prohibitive for business owners, you can’t just rip out your relational database. A lower risk, gradual transition to a target architecture often wins the day. Streaming, Caching & CDC technologies are vital tools for this journey. CDC (Change Data Capture) can turn your legacy data stores into streaming sources. Modern caching technologies can host data in a way that provides speed and scalability, and finally streaming acts as the glue that can drive new use cases as well as bridging the old. The talk is a practical introduction to CDC (Change Data Capture). It covers an architecture, trade-offs, tooling, and demos.
