As part of engagement, I wrote this SAS SPD translator here teiid-marketplace/sas · GitHub This translator is not fully complete, however it is functional. It uses the JDBC translator that SAS provides. This is not part of the Teiid build yet, because I do not have access to a SAS environment. You can give this a try. To use this download the source code and compile it, and it should provide you with a zip file that you can unzip over the installation. Then add a translator entry in the standalone-teiid.xml file under "teiid" subsystem, you should be good to use it.
If you find any errors, I will certainly accept any patches. So, it is on our roadmap, but target version is still TBD.
