Subject [jira] [Updated] (IGNITE-6069) Service versioning
Date Tue, 15 Aug 2017 23:21:00 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-6069?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Denis Magda updated IGNITE-6069:
--------------------------------
    Description: 
Make services upgradable -again-. 

Main points:
- compute binary type ID by (classname + version)
- use serialVersionUuid as version ( ?)
- all service instances with the same name must have the same version
- make ServiceProxy aware of versions and upgrade process, pause requests while service is
being upgraded
- extend Service interface (UpgradableService?) - add ability to collect state of previous
version before start.

Once the feature is implemented, it has to be documented extensively.
