protostream | serialization library based on Protocol Buffers | Serialization library

I am trying to update a big project that was using Infinispan 7 to the v10.1.3.

I would like to use the new protostream marshaller, but I don't understand how to be able to use UUID as cache key, or even (easier ?) as a field in a class that I want to insert in a cache.

My cache was accessed like that : Map testUUIDAsKey = manager.getCache("t1");

Here when trying to put a value into the cache, infinispan tells me that he don't know how to marshal an uuid.

Ok, so after reading the documentation, I tryied to switch to a easier test case : Map testUUIDAsField = manager.getCache("t2");

Here, the Bar class have a field of type UUID, and I tried to use the protostream annotation processor that will generated and build a proto file automatically when the right annotation are used.

But this time, the annotation processor tells me that UUID class must be instantiable using an accessible no-argument constructor.

I know that protobuf can't manage UUID, I can store the value as string or by storing the 2 long values part of an uuid.

How can I register a UUID marshaller that would use String as it representation in the end ?

And how can I tell the annotation processor that it must use this marshaller ?

Then, how can I use UUID as a key ?

Thanks.

I have a problem using Infinispan 9.4.0/9.4.1 with Hot Rod Client and Protobuf protocol in order to be able to use queries.

This is my cache configuration:

Note: I've narrowed the problem down, and rewritten the question

I am trying to use Infinispan (in the guise of JBoss Data Grid) in Karaf (in the guise of JBoss Fuse) and hitting a wall when it comes to the protostream dependency. I wonder if anyone out there can tell me what I'm doing wrong.

I have boiled my problem down to a sample project here: https://github.com/batwad/infinispan-fuse-example

The project contains a blueprint which declares two beans: a factory for creating an Infinispan RemoteCache and a bean produced by the factory for accessing the default cache. There's also an example entity with protostream annotations and a feature file to install it.

When the feature is installed it looks good:
