Imagine having a tool that can automatically detect if you are using JPA and Hibernate properly.
Hypersistence Optimizer is that tool!
Recently, I got a very interesting request from one of my readers. Since I’ve been providing many custom types to support JSON, ARRAY or nullable Character types, I decided to start a new open-source project to make it easier for you to get this extra Hibernate Types.
Kudos to @vlad_mihalcea, the Hibernate Types library saved me tons of work yesterday by automagically mapping the PostgreSQL jsonb column to a POJO. Brilliant work 💪
Based on my book, High-Performance Java Persistence, this workshop teaches you various data access performance optimizations from JDBC, to JPA, Hibernate and jOOQ for the major rational database systems (e.g. Oracle, SQL Server, MySQL and PostgreSQL).
The SQL Master Class for Java Developers training is aimed to level up your SQL skills with techniques such as Window Functions, recursive queries, Pivoting, JSON processing, and many other database querying features supported by Oracle, SQL Server, MySQL, or PostgreSQL.
