You can review this slide deck for an overview of our story.
We currently do not support Thrift and are prioritizing support for HTTP and gRPC traffic.
We are currently working on our support for encrypted in-cluster traffic and plan to release it in Beta in Q1'20.
Ingesting data from Prometheus is part of our roadmap but is not currently supported.
We are working on a data access API and will be releasing it to Beta soon. In the interim, you can use the CLI's query support to use as an API replacement.
