------------------------------------------
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).
