What this PR does / why we need it:

This PR adds a go server as a subprocess in the feature store so that on get_online_features() call, features are served via the go subprocess instead of the python server. The go subprocess will be spun up on the first time get_online_features() is called from the python program and will start serving from there. Currently, feast serve and ODFVs are not supported by the go server. Eventually, the hope is that go server will serve features faster than python server.

As for future work, we have a working code for feast serve and a python plugin connector and are working on some benchmarkings to add goroutines and replace some current functions with more optimized implementations to potentially speed up the go server, but we're open to suggestions on but not limited to coding styles, bugs, and potential optimizations.

A few things to mention regarding to the latency when starting go server:

  • The current implementation tries to connect to go server 5 seconds and stops to establish a go server, but I've noticed that sometimes it needs more time to start. This is problematic if we want to automate tests with go server since sometimes go server cannot be started and throw a connection exception and tests fail while it might work properly. I'm open to suggestions on how to make this implementation more robust as well as discussions around trade-off between latency and robustness.
  • This latency needs to increase once the python plugin connector is added since local experiments show that it can take up to 8 seconds.

Does this PR introduce a user-facing change?:

user can add go_feature_server attribute in their feature_store.yaml configuration file to enable using go server on get_online_features()

Should we use plain english for the error message instead of an error name?

This is needed to pass one of the integration tests that requires FeatureNameCollision exception from python sdk. I hacked around by parsing error message to coordinate between 2 languages but would there be a better coordination method I should use instead?

I just want to prevent polluting the Golang SDK with Python specific requirements. At the very least a translation layer would be useful here to go from a Go error message to this Python one, even if it's hardcoded. It may also be a good idea to eventually introduce error codes instead of having to parse strings.
