In Relation To

In our previous post, we showed how @Mutability(Immutability.class) and removing CascadeType.MERGE cut our JSON processing time in half by eliminating unnecessary dirty-checking. That was the first round of optimization. This post covers the second round enabling Hibernate’s second-level cache on the same entity, and the surprising discovery that three annotations must work together to unlock the full benefit. Getting two out of three still left us over 8x slower than the final result.
