Java persistence is a critical component of any Java application, enabling developers to store and retrieve data from various data sources. However, as applications grow in complexity and scale, persistence can become a significant bottleneck. Traditional Java persistence approaches, such as using Hibernate or JPA, can lead to performance issues, scalability limitations, and complexity.

It compares Single Table, Joined, and Table-Per-Class strategies, highlighting how Joined inheritance introduces massive hidden performance costs due to deep SQL table joins. Resolving the Notorious N+1 Query Problem
