May 26, 2023 · The disadvantage of this inheritance mapping method is that retrieving entities requires joins between tables, which can result in lower performance for large numbers of records. The number of joins is higher when querying the parent class because it will join with every single related child — so performance is more likely to be affected the ^{Dec 22, 2014 · Because of multiple inheritance there is chance of the root object getting created more than once.
