Infinispan at Devoxx France 2024

Infinispan 15 in Devoxx France

This month we participated in one of the biggest developers conference in Europe: Devoxx France in Paris.

Infinispan did not have a specific talk, however it was present indirectly in two talks:

Highly available Identity and Access Management with multi-site Keycloak deployments in the cloud


A single sign on solution for your customers and employees shouldn’t be a single-point-of-failure in your architecture. Keycloak, a popular Open Source Identity and Access Management solution that provides single sign on, amongst other capabilities, is no exception to this. A clustered Keycloak deployment in a single site or datacenter provides sufficient availability for many. An increasing number of organizations need to utilize multiple sites for improved resiliency or to meet legal requirements. In 2023, Keycloak overhauled its multi-site capabilities for public cloud infrastructures, tested them thoroughly and provided deployment blueprints to the community. They show how to set up an AWS infrastructure and deploy Keycloak across multiple sites. This talk presents, from an architects and developer perspective, how we approached the problem, which architecture we chose, the challenges we faced and which tools helped us along the way. Expect to dive into concepts like load shedding, cache stampedes, and automated failover. See tools like Gatling, Helm, OpenTelemetry, Kubernetes Operators and AWS infrastructure in action. We will also provide an outlook for the next steps in our journey. These insights will help you to improve your Keycloak deployments as well as design and test your own applications so they can withstand high load and site failures.



During this presentation, Alexander Schwartz and Ryan Emerson delve into the latest version of Keycloak and the High Availability architecture that facilitates deploying two sites with Keycloak.


A key component enabling this architecture is the Infinispan Server, with its Cross-Site replication capabilities.

This capability is used to provide Active-Passive replication, however the roadmap includes plans for Active-Active replication in the near future.

Hibernate Search 7.0 was released in late 2023, and version 7.1 is already available. Discover all the new features of this latest version and practical use cases such as vectorial search (kNN), which enables the implementation of textual, audio, or image-based machine learning search. This conference will guide you through the underlying changes, demonstrate concrete use cases, and provide practical tips to make the most of the latest version of this essential library for data persistence and full-text search in the Java ecosystem.

Hibernate Search


In the talk, Infinispan was mentioned to highlight that Hibernate Search can function as a standalone component in a Java Application, independent of Hibernate ORM. Infinispan utilizes the Hibernate Search library to implement Full-Text search over cache values. Moreover, since Infinispan 15.0, it can be used as an embedding store to execute vector search with Langchain and Langchain4j.
