Vectroid is pure Java solution based on modified version of Lucene. We use a custom built FileSystem to work directly with GCS (Google cloud object store). It is a terraform/helm managed Kubernetes deployment.

Interesting, perhaps, you can write a blog post about it. It would be interesting to read about what kind of changes you made to Lucene.
