*@Anthony-* *> The server should be smart enough to figure out what's in my bundle and understand how to deploy it including any dependencies*
Agreed on the dependencies part, but... "*smart enough to figure out what's in my bundle*". Hmmm. Beyond recognizing Geode/GemFire objects/interfaces, I don't see how this is likely. For instance, I recently added the ability (SGF-106 <https://jira.spring.io/browse/SGF-106> [1]) in SDG to create Indexes using Annotations on application domain objects/entities properties/fields when using the SDG mapping support <http://docs.spring.io/spring-data-gemfire/docs/current/reference/html/#mapping> [2] (and SD *Repositories*). Currently, Geode/GemFire does not even recognize SDG "defined" (annotated) Functions. How is it going to know (or how I am I going tell it) about Index annotations now, or something else. Of course, Geode/GemFire could delegate to the *Spring* container in both instances, but that does not cover cases where *Spring* is not used.
