This document provides an overview and agenda for a presentation on Spring Data and in-memory data management using Apache Geode. The presentation will cover Apache Geode functionality, integrating Geode with Spring frameworks, and examples of caching, events, data access and improvements in Geode and related projects. It lists caching, scalability, availability and other capabilities of Geode. The roadmap discusses upcoming versions of Spring Data GemFire and Geode as well as integration with Spring Boot, Session and other projects.
