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