As the organizers of Flink Forward, and the original creators of Apache Flink, Ververica kicked off the opening session with a journey through the Past, Present and Future of Apache Flink.
Starting with Stephan Ewan, Co-creator of Flink, Apache Flink PMC member, and Founder of Restate, and Feng Wang, Senior Director of Engineering at Alibaba and Apache Flink Committer, we explored a brief history of how Flink became what we recognize today, from the start of the initial Stratosphere Project at the Technical University of Berlin, through the merge of Flink and Blink at Alibaba, and into the future of unified streaming and batch processing capabilities.
Joining the stage next, Siddhartha Choudhury from Booking.com and Sudha Ramraj from Uniper shared how their companies are using Flink and Ververica to serve their data streaming needs.
Each then described the specific use cases they are solving with this technology and the positive impact Flink has had on internal team enablement.
Next, Mark Pybus (Evoura), Erik Schmiegelow (Hivemind Technologies), Filip Yonov (Aiven), and Sijie Guo (StreamNative), joined Ververica's Field CTO, Ben Gamble and Partner Alliance Manager, Chris Horsnell to discuss the importance of Partners and when users should consider introducing Flink into their organizations. The Partner panel discussed the massive requirements related to data size and speed that businesses face, and how real-time data is still not widely adopted by data engineers and organizations that are more comfortable with batch processing and ETL. They shared their insights on how businesses can successfully adopt real-time data processing with Flink to solve complicated use cases.
The final part of the Opening Session featured two major announcements and an exciting introduction.
First, Jark Wu, Head of Flink SQL at Alibaba Cloud, Apache Flink PMC Member and Committer introduced Fluss (Flink Unified Streaming Storage), which promises streaming storage for next-gen data analytics. Fluss is engineered to offer a high-performance, scalable, and fully integrated solution for real-time data processing with Apache Flink, further driving towards a complete unified batch and streaming data platform.
Learn more about Fluss in the new blog.
Next up, Igor Kersic, Head of Product at Ververica, took the stage to introduce Ververica’s newest deployment option: Bring Your Own Cloud. This deployment provides a managed experience that uses your existing cloud resources to leverage the flexibility and scalability of Ververica’s Unified Streaming Data Platform while maintaining full control over your cloud infrastructure. This new deployment option joins Self-Managed and Self-Service options, and provides an effective solution that aligns with zero trust principles. With BYOC, you retain absolute data sovereignty, as your data is stored in object storage and hosted on a cloud environment fully controlled by your organization, ensuring full oversight and security.

The final part of the Opening Session featured two major announcements and an exciting introduction.
There were plenty of surprises in store at Flink Forward Berlin, but one of the most exciting was the official announcement of the release of Apache Flink 2.0! Feng Wong returned to the stage alongside Ververica’s CEO, Alexander Walden, and presented what Flink users can expect from 2.0.
One major new feature is the decoupling of compute and storage resources by using a Distributed File Systems (DFS) as the primary storage. Users will benefit in multiple ways
Another very exciting introduction are Materialized tables, designed to simplify the development of data processing pipelines by allowing uniform SQL operations and automatic data freshness management. Now, users can define batch and streaming transformations to data in the same way, accelerate ETL pipeline development, and manage task scheduling automatically.
In short, by modernizing its legacy components, embracing disaggregated state storage, and enhancing integrations with projects like Apache Paimon, Flink 2.0 is setting new standards for what's possible. We are confident that Flink 2.0 will provide more efficient, scalable, and unified data processing for a growing number of use cases and businesses. Ready to learn more?
