The document presents an overview of implementing Apache Geode with Spring Data, detailing its historical versions and the emphasis on simplicity and ease of use. It covers the use of annotation-based configuration, various client and server annotations, and features within Spring Data Geode 2.0. Additionally, it outlines future enhancements and integrates different repository functionalities including paging, sorting, and query projections.

How does it work?
New Annotation-based Configuration
 Convention over Configuration
 Use sensible defaults for all configuration parameters OOTB
 Enable users to get up and running, quickly and easily (no hassle).
 Allow user to override and customize the default, provided configuration
