For example https://github.com/CoatiSoftware/SourcetrailPythonIndexer and under the hood the file format is SQLite: https://github.com/CoatiSoftware/SourcetrailDB

  • GitHub repo serving

    A flexible, high-performance serving system for machine learning models

    Project mention: Exposing Tensorflow Serving’s gRPC Endpoints on Amazon EKS | dev.to | 2021-02-10

    gRPC only connects to a host and port — but we can use whatever service route we want. Above I use the path we configured in our k8s ingress object: /service1, and overwrite the base configuration provided by tensorflow serving. When we call the tfserving_metadata function above, we specify /service1 as an argument.
