Hi Jayesh- Continuing on with your second question...
*> 2. Assuming that my first deployment of project was POC-1.0.0.jar release, how I should organize code for next release with only few new regions?* Well, depends on whether you prefer to use *Spring* config or not. If you prefer *Spring* config (XML/Java) then you will need to bounce your servers no matter what. Otherwise, if you prefer not to, or are unable to, restart your servers, then you must use *Gfsh* to configure new Regions. Geode's *Cluster Configuration* service handles the organization of the configuration (artifacts) for you. CC will also handle applying the configuration to any newly added servers, *Spring*-based or otherwise, providing you enable the use of Cluster Configuration service for Geode Servers configured with Spring as I explained previously. The whole point of using *Gfsh* is not to worry about the "configuration artifacts" and where they are maintained. So, you do not need to worry about this... *> I found that we can deploy some jars to server using gfsh deploy, but i am not sure about folder structure it should follow.* You should not muck working directory folder structure setup by Geode when the server/node starts. You should retain this working directory as is from which you launched your server (*Spring Boot*, *Gfsh*, or otherwise) since it will contain the config files and other artifacts (e.g. deployed JARs, possibly *DiskStore* files depending on your configuration, etc). Inside your JAR file, the organization does not matter; i.e. follow normal Java JAR semantics. This... *> **Also if that would also be spring boot project with <gfe:region..> tags only without Spring Boot Main?* ... does not apply to new Regions; you must add new Regions to existing, running servers via *Gfsh*. -John On Wed, Sep 6, 2017 at 2:00 PM, John Blum <[email protected]> wrote: > Hi Jayesh- > > Sorry for the delayed response; I was on VAC for the past couple weeks. > > I would also suggest if you have critical questions involving both > *Spring* with Apache Geode or Pivotal GemFire, that *StackOverflow* [1] > is a much better forum than Apache's antiquated mailing lists.
