Description

Hello Vespa Team, Can you please consider support a properties-file which is available during run-time along with the model ? So some meta-data e.g. threshold/label, etc can be associated with the model. This is for the stateless evaluation of the models like (XGBoost, TensorFlow, Onnx, etc) which is supported in vespa.

Thank you, Pinank

Contributor guide

Research direction
Investigate how Vespa loads and evaluates ML models at runtime, and propose a mechanism to associate a properties file with each model. Look into the existing model configuration and stateless evaluation code paths in the Vespa codebase.
