Database partitioning improves query performance for large datasets by splitting tables into smaller, manageable segments. Hibernate 6.2+ introduces the @PartitionKey annotation to optimize queries on partitioned tables. The tutorial demonstrates setting up PostgreSQL table partitions, configuring Spring Boot with Hibernate entities using @PartitionKey, and creating REST endpoints to interact with partitioned data. Key benefits are realized when queries include the partition key in WHERE clauses, allowing the database to target specific partitions rather than scanning all data.
