[jira] [Created] (IGNITE-19549) Handle wrap-around of Catalog object IDs

Roman Puchkovskiy created IGNITE-19549:
------------------------------------------

             Summary: 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
             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).
