Re: [jakartaee-platform-dev] [External] : Additional profiles

Well, my suggestion is to move MP Config to Jakarta and put it under core profile and then MP can directly get it back. I am also fine not to put config in the core but not having two configs. Anyway, I think this discussion needs to happen under CN4J.

What is your idea? How shall we deal with Config in Jakarta EE?

I disagree with creating a Jakarta Config, which creates a competing message with MicroProfile Config. When MP consumes this core profile, it will have two configs to deal with.

MP Config is not huge and I don't see the value to further split it.

I agree that Config must be in Core profile, but I disagree that it should be MP Config. IMO, it must be Jakarta EE spec. Depending on a spec from another project brings many disadvantages and Jakarta is all about stability and backwards compatibility.

I think it should be a new spec which MP Config should possibly extend. It can be very minimalistic like one @ConfigValue annotation. So, there is a similar relationship as between @Inject spec and CDI. Or it can contain the most stable features of MP Config.

Hi,

MP Config of course only given a sufficient stable and guaranteed release plan for Jakarta.

I'd almost say this Core profile should be governed by its own working group, who take into account the interests of both EE and MP, being a core profile for them both. 

Now I know we can't have yet another actual working group, but such Core profile (should it come to fruition in this form) probably benefits from such shared interest governance.

Kind regards,

-1 for MP Config.

 

Unless the MP Folks can commit on „mature Features“ (a bi like the maturity Level of CNCF) that won’t suddenly receive breaking changes and they also guarantee to provide a Jakarta first Roadmap where e.g. MP Config is migrated to the „jakarta“ Namespace and newest Jakarta release ASAP before any other MP specs it is not ready to be included in any Jakarta EE profile I’m afraid.

 

Implementations may use it at their own risk but we already see how badly that affects and slows down Jakarta NoSQL and its implementations.

Betreff: Re: [jakartaee-platform-dev] [External] : Additional profiles

 

Hi,

 

Just thinking about Core from another perspective, is having it contain exactly what EE and MP have in common.

 

So that could be, for now:

 

Jakarta REST

Jakarta JSON-P/B

Jakarta CDI

Jakarta Security

MP Config

 

Following this Core profile, both the rest of EE and the rest of MP could depend on it.

 

Thoughts?

 

Kind regards,

Arjan Tijms

I agree persistence is too much for Core. While the issue is that most microservices do persist data, the sources are often varied including simply messaging and some microservices merely perform orchestration of one kind or the other.

OTOH, when I look the JNoSQL stuff and compare that with current Persistence, I think, it would probably make sense to define sth like "persistence-core" containing annotations common to both of them + some lightweight EntityManager/EntityManagerFactory like interface(s) offering just basic CRUD operations with some unwrap method eventually and nothing more. A Map.Entry or an item in the List could then be seen as trivial implementation of the "Entity" from the "persistence-core". It could be even part of existing common-annotations API. Seeing jakarta.persistence.Entity and jakarta.nosql.mapping.Entity together reminded me times figuring out what type of Node is the code I have to work with using - is it org.w3c.dom.Node or javax/jakarta.xml.soap.Node? - and that can be confusing for users in some cases in the future.

The problem is that the dust hasn’t quite settled yet and there are several options that make sense to one extent or the other: thin wars, fat/uber jars and hollow jars. I bet it would be hard to get complete consensus on which deployment models should be required.

In addition, a fully Java/annotation way of configuration could also be explored but I think it is a lower priority. If you look at Spring Boot specifically, the properties based configuration mechanism seems to have won out for the most part. In order to get the Core Profile out in time for Quarkus perhaps it is best to leave configuration unspecified at least initially.

I think it should help make the discussion a bit easier. All options are workable, but this would be the order for me: A2, A1, B, C. B I think carries too many unnecessary risks and complexities. C I think really sends a poor message to the community as to the relationship between Jakarta EE and MicroProfile. I think effectively what you are proposing is C.

It will provide maximum portability between Jakarta profiles. On the other hand it’s an overhead for the smallest profile. In the most cases microservice is one application, so multiple applications support maybe not needed. XML-based deployment descriptors are something from the last century. We actually don’t want to include any XML processing specs to the core profile and even made them optional in the main Jakarta profile. I am trying to say that maybe deployment specification needs a rework to support more modern approach like yaml or json files or even be based on configuration spec. It’s one of the options. Another option would be using executable jar files the same way as in Spring Boot, Helidon, Quarkus, etc. This approach has many advantages such as unnecessary class loading madness, potential GraalVM native-image support, etc.

IMO, Jakarta profile must use/depend on Jakarta specifications only. Recently I talked with Tomas Langer (Helidon architect) and he had an idea of creating a minimalistic config specification in Jakarta which contains one annotation - @ConfigValue. More functionality can be added later. MicroProfile Config can depend on Jakarta Config. It will make possible using MP Config implementations in Core Profile implementations. It makes sense to me.

By the way, I don't want to see EJB on the Core profile list. CDI is the replacement for EJB.
