I'm currently trying to migrate from Quarkus 2 to Quarkus 3.
I performed all the needed changes and the code now compiles with Quarkus 3.
I'm using Hibernate Reactive Panache with the Repository Pattern.
I have one entity that needs to fetch data from a lot of tables, so the entities it needs are using FetchType.EAGER. To make matters worse, this one entity can have multiple types, so I basically have 4 subclasses of this abstract class and I was serializing them all in one table using the annotations @Inheritance(strategy = InheritanceType.SINGLE_TABLE) and @DiscriminatorColumn(name = "type") and on each subclass using @DiscriminatorValue(<name>).
With Quarkus 2 the query to retrieve all data was able to retrieve them all, but now with Quarkus 3 and the listAllmethod I get a GenericJDBCException stating Too many tables; MySQL can only use 61 tables in a join, even though I haven't changed the logic here, just went from a findAll to a listAll.
Here is a picture of the ER Diagram with the classes that are fetched from this class (named Request).
Each RequestType subclass has a different amount of RequestSlot
Any ideas on what can I do or on what is happening here?
Thanks in advance
