Hi Isuru, What kind of properties are you referring to where this would be the case ? Is there an actual use case for this ? Which code in stratos would actually take these properties into account and apply them ?
Thanks Martin From: isu...@wso2.com [mailto:isu...@wso2.com] On Behalf Of Isuru Haththotuwa Sent: Sunday, September 21, 2014 1:05 AM To: dev Subject: [Discuss] [Grouping] Specifying Dependency Information in Group Definition Hi Devs, In Service Grouping, a cartridge that is depending on another might need some information (endpoint, etc.) about the latter. AFAIU this information will be specific to a Service in a Group. Therefore, I suggest we add this properties to the cartridges section of the Group definition. I have shown a simple Group Definition with the proposed changes [1]. Here, dynamicProperties contains the names of properties of which values should be dynamically picked at the runtime. If a user needs custom properties, we should define a abstraction so that a custom implementation can be loaded at the runtime. The per-defined property name-value pairs are defined in the staticProperties section. These data can be published to the meta data service. The relevant member instances can query them and get the information about the dependencies. Handling this information would be done at the instance level (using Cartridge Agent, etc.). Please share your feedback.
