Description

While we are code freeze for 4.0.0 release (it took nearly month for several reason), WSO2 Private PaaS team used Stratos RC and make some enhancement for support clustering and WKA member handling in Stratos. Also implemented simple grouping functionality (full featured grouping functionality is implementing @4.1.0 release) which we need simple grouping in cartridges like MongoDB, MySQL master/slave ..etc.

With above changes, Stratos can define Cartridge which need clustering and it provide functionality to define WKA (well known address) members. Autoscaler take care of these members (maintaining minimum member required) and other members join with WKA members and join cluster for caching and etc.
