> {{PropertyIndexEditor}} when configured for unique index maintains an in
> memory state of indexed property in {{keysToCheckForUniqueness}}. This set
> would accumulate all the unique values being indexed.
> In case of upgrade where the complete upgrade is performed in single commit
> this state can become very large. Further later while exiting the editor
> validates that all such values are actually unique by iterating over all such
> values.
> We should look into other possible ways to enforce uniqueness constraint
