             Summary: Provide a gRPC service for accessing OTS funtionality
                 Key: JBTM-3102
                 URL: https://issues.jboss.org/browse/JBTM-3102
             Project: JBoss Transaction Manager
          Issue Type: Feature Request
          Components: JTS
    Affects Versions: 5.9.2.Final
            Reporter: Michael Musgrove
            Assignee: Michael Musgrove
             Fix For: 5.later


JTS was the Java EE standard for different JTA implementations to interoperate. Since CORBA (and therefore JTS) is now an optional component of Jakarta EE there is a need for an alternative specification for how services can propagate a transaction context. A popular alternative to CORBA is gRPC which has the following nice features: 1) it is a good technology choice for service to service interactions; 2) is polyglot or, as stated in the documentation, "Automatically generates idiomatic client and server stubs for your service in a variety of languages and platforms"; and 3) provides excellent performance.

The reason JTS was chosen as the Java EE interop standard is that 1) it provides language level bindings that enable interoperability; and 2) it builds on a pre-existing industry standard, namely OTS.

Consequently, it is reasonable to conclude that a mapping from CosTransactions.idl (the IDL definition for OTS) to Protocol Buffers and gRPC services will:

- Enable existing OTS/JTS implementations to provide service in these new environments.
- Enable new and existing gRPC services to be able to access transactional functionality in an interoperable manner.
