Mixed MFA and RFA API Compatibility

Peter Chan

Our application is currently using RFA for both pub and sub. There is a mix of C++ and Java applications.

We have a project to introduce some new pub / sub and disable some old pub. Eventually we're looking at upgrading all our APIs to EMA. However, due to resources and time constraint we're considering a phased migration where we might have the following combinations:

- A Java application with sub using RFA Java 1.8 and pub using EMA Java 3.x at the same time

- A C++ application with sub using RFA C++ 8.x listening to pub from another application using EMA Java 3.x

Would be much grateful if Refinitiv could confirm if the above combinations are supported. This is very critical to our architecture design and planning of the API upgrade path.

Hello @Peter Chan

Could you please clarify "RFA Java 1.8"? Do you mean RFA Java version 8.x?

If so, the RFA OMM interface can connect and consume data from the EMA Interactive Provider using the RSSL connection because they both use the RWF data format.

About Java 1.8 (or Java 8), based on the RTSDK Java README file, starting with Q3 2023, with version RTSDK-2.1.2.L1 (next version), RTSDK drop support for OpenJDK/JDK 1.8. Please plan to upgrade your JDK version.

• Note "the current" support JDK versions are: Oracle JDK 1.8, 1.11 & 1.17, OpenJDK 1.8, 1.11 & 1.17, Amazon Corretto 8 & 11.
