Event Store was first developed back in 2011 by Greg Young, a pioneer of CQRS and event sourcing. This was done in a joint effort with BathASU, a pharmaceutical compounding company based in Bath, UK. At the time BathASU had a strong business case for adopting event sourcing and hired Greg to help them build a new system. Rather than build “yet another event store”, as Greg had done on many previous occasions, an open-source project was started and the resulting Event Store database was made available in 2012.
Due to demand, Event Store began offering a commercial support option and slowly grew a strong customer base of organizations such as Walmart/Jet.com, Xero Accounting Systems, UK NHS (National Health Service), checkout.com, and CERN. Since that time, Event Store has been deployed in thousands of production clusters, running mission-critical, high value, web-scale workloads around the world.
In late 2018, Event Store saw increased evidence for the potential of event sourcing’s impact on the development of modern distributed systems. Event Store decided to expand investment towards a more ambitious vision across multiple areas including:-
- Advancing the database technology itself
- Improving documentation and usability
- Expanding the scope towards the larger context of what is needed to build event-sourced systems
- Substantially improving operability (including cloud base services)
- And much more
To accomplish this renewed ambition, Event Store substantially grew its development and support capabilities and will continue to grow over the coming years.
The results of this growth can already be seen with the upcoming Event Store 20.02 release which is packed with improvements and features including:-
- Move to .NET Core 3.1
- New gRPC clients for Java, C#, Node, Go, and Rust (with more to come)
- Server-side filtering
- Numerous bug fixes and performance improvements
This release is just the beginning of the next phase for Event Store. The underlying event-sourcing data model is gaining increased traction and recognition, and although historically it has been difficult to build and run these types of systems, especially at scale, Event Store wants to make it easier.
Event Store looks to provide a world-class database technology on par with the top database technologies in the industry. And alongside this, plugins and tooling for every major programming stack to help developers and operators successfully implement and run distributed systems.
Event Store Cloud, releasing later this year, will be a key milestone in the effort to get up and running with Event Store. It represents one of the key initiatives you will see as Event Store moves forward as an increasingly relevant and important alternative database technology for modern applications.
Event Store is growing, so if you are interested in participating check out the careers page or consider participating in other ways such as joining our guest writer program, contributing to the open-source project, or speaking at meetups on Event Store or event sourcing.
