MultiTenancy using Hibernate in Spring Data JPA

  • MultiTenancy is a feature of JPA that allows you to store database data across multiple tenants. It's not a new concept—many applications have used it for years to separate data by tenant. However, Spring Data JPA provides an easy way to use multi-tenancy in your application by using Hibernate as your persistence provider.

  • This allows you to create a single entity class that can be shared by multiple tenants, giving each tenant its own independent instance of the data.

Let's see how it works by using three different approaches:

  • Partition tables by tenant id. → Single table having partition (Supported Only from Hibernate 6)

  • Use a separate schema per tenant. → Single Database having multiple schemas

  • Use a separate database per tenant. → Different Databases having same schema (Could be having different aws regions)
