This document summarizes a presentation about using Protocol Buffers (Protobuf) with Spring caches and Infinispan. It discusses how Infinispan is an open-source, in-memory distributed data cache that supports interoperability and fault tolerance. It also explains that Infinispan supports different data formats including Protobuf, and describes how the Protostream API and Protobuf definition files can be used to serialize Java objects to Protobuf format in Infinispan caches. Finally, it mentions a demo of using Spring Boot, Infinispan and Protobuf caches that implements cross-site replication between different data centers.
