             Summary: Switch distribution zone IDs from UUID to int
                 Key: IGNITE-19548
                 URL: https://issues.apache.org/jira/browse/IGNITE-19548
             Project: Ignite
          Issue Type: Improvement
            Reporter: Roman Puchkovskiy
             Fix For: 3.0.0-beta2


Currently, as zones are stored as named list items in the Configuration, they are internally (to the configuration) identified by UUIDs. The same UUIDs are also used to identify zones in the whole system.

We need to change the latter: that is, in addition to the internal IDs (needed only for configuration), we need to generate integer IDs and use them in the rest of the system to identify zones.

For now, zone IDs should be generated using same global counter that will be used to generate table and index IDs.

Internal IDs will remain until we switch from storing tables/indices/zones in the Configuration to storing them in the Catalog (this is out of scope of this task).
