Resolution: Duplicate
> Handle wrap-around of Catalog object IDs
> ----------------------------------------
>
> Key: IGNITE-19549
> URL: https://issues.apache.org/jira/browse/IGNITE-19549
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
>
> We are planning to switch from UUIDs to ints as Catalog object (tables,
> indices, zones, views) IDs (IGNITE-19524). int allows 2/4 billion of values
> (approx); if we add columns to the category of objects that need these IDs,
> it seems theoretically possible to get into wrap-around situation.
> Design of some mechanism might be needed.
> (Although, in practice, it seems that WA cannot happen).
