------------------------------------------
Looks good!
> Switch table IDs from UUIDs to integers
> ---------------------------------------

> Key: IGNITE-19531
> URL: https://issues.apache.org/jira/browse/IGNITE-19531
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy

> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-beta2

> Time Spent: 50m

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