> PHOENIX-5132 changed the ViewIndexId generation logic to use one sequence per physical
view index table, whereas before it had been tenant + physical table. This removed the possibility
of a tenant view index and a global view index having colliding ViewIndexIds.
> However, existing Phoenix environments may have already created tenant-owned view index
ids using the old sequence, and under PHOENIX-5132 if they create another, its ViewIndexId
will got back to MIN_VALUE, which could cause a collision with an existing view index id.
