[teiid-dev] UDF Related Changes in 7.0 Teiid

In Teiid user defined functions (UDF) are defined in a special "FunctionDefinitions.xmi" file and this file deployed in the Teiid runtime. Some times there is jar file associated with to provide implementation classes, and if all the functions are "push down" then it may not require it. Lack of name space based functions like per VDB functions, or per Connector kind of functions were long standing requests from users (TEIID-231, TEIID-502). Now in the container environment with its free standing nature this file causes trouble in terms of deploying a UDF. In 7.0, we going to bundle this "FunctionDefinitions.xmi" file inside the VDB artifact, such that each VDB can have its own UDF functions and at the same time solve the deployment issues. The tooling in the Designer 7.0 will be modified to include "FunctionDefinitions.xmi" file in the VDB and Teiid runtime will be modified to look for the "FunctionDefinitions.xmi" file inside VDB and deploy it accordingly.
