   ### Query engine
   
   Iceberg-Core Java
   
   ### Question
   
   We are using the table snapshot rollback functionality of the iceberg-core 
java library. Rolling back to a previous snapshot works as expected, but I’m 
unsure how the current-schema-id is intended to behave in this context. In our 
case, it always points to the latest schema.
   
   How is this supposed to work in principle? What happens if we need to roll 
back to a snapshot that uses an older schema version—for example, if breaking 
changes were accidentally introduced during schema evolution?
