This simple Go service generates load as part of the Feast testing suite. It sits between an HTTP based load testing tool as follows:

[Load Testing Tool] --(http)--> [Feast Load Test Proxy] --(grpc)--> [Feast Serving]

Create a specification file for the load. Refer to the example specification for details.

LOAD_SPECIFICATION_PATH=example/loadSpec.yml

Start the proxy

LOAD_FEAST_SERVING_HOST=feast.serving.example.com LOAD_FEAST_SERVING_PORT=6566 go run main.go
