@@ -346,6 +346,7 @@ Modules with their own `pom.xml` that run plain Hibernate without the Spring Boo
| [`inheritance`](inheritance/) | `SINGLE_TABLE` vs `JOINED` vs `TABLE_PER_CLASS` vs `@MappedSuperclass`: generated DDL, SQL, failures and timings (Hibernate `7.4.13.Final`) |
| [`locking`](locking/) | Optimistic (`@Version`, retries) vs pessimistic (`PESSIMISTIC_WRITE`, `NOWAIT`, `SKIP LOCKED`) locking, lost updates and deadlocks on H2 (Hibernate `7.4.14.Final`) |
| [`soft-delete`](soft-delete/) | `@SoftDelete` (`DELETED` / `ACTIVE` / `TIMESTAMP`) vs `@SQLDelete` + `@SQLRestriction`: generated SQL, restore, unique constraints, associations, native-query bypass and Spring Data JPA, on H2 and PostgreSQL 17 (Hibernate `7.4.14.Final`; unlike the others this module uses the Spring Boot 4.1.1 parent, for the Spring Data tests) |
| [`id-generation`](id-generation/) | IDENTITY vs SEQUENCE vs UUID (random, `Style.TIME`, v7): the SQL each produces, why IDENTITY disables JDBC batching, pooled optimizer and `allocationSize` mismatches, and Spring Data's extra SELECT on assigned ids, on H2 (PostgreSQL parts skipped, no Docker); see [the article](https://ankurm.com/hibernate-id-generation-identity-sequence-uuid-v7-batch-inserts/) |
| [`migration-5-to-7`](migration-5-to-7/) | Hibernate `5.6.15.Final` vs `7.4.14.Final`: jar diff, Hibernate 5 code compiled against both, schema defaults, `hbm2ddl` validation of a Hibernate 5 schema, and cheat-sheet snippets |
| [`multitenancy`](multitenancy/) | Hibernate 7 multi-tenancy on Spring Boot 4.1.2: `@TenantId` discriminator vs schema-per-tenant (shared pool with `search_path`, and pool per tenant), tenant from a JWT claim, the `search_path` leak and the no-tenant failure modes, on PostgreSQL 17 (Hibernate `7.4.14.Final`) |
| [`json-columns`](json-columns/) | JSON columns in Hibernate 7.4: `@JdbcTypeCode(SqlTypes.JSON)` for Map / List / record / POJO / `@Embeddable`, `json` vs `jsonb` DDL, HQL JSON functions, native JSONB operators, GIN and expression indexes with `EXPLAIN`, dirty checking, Jackson 3 vs Jackson 2 `FormatMapper`, MySQL 8.0, on PostgreSQL 18 (Hibernate `7.4.14.Final`, Spring Boot `4.1.2`) |
