Support for other HTTP based protocols like GRPC

[ramey]

Problem

Currently, Raccoon only supports Data ingestion using WebSockets and protobufs as the only supported data serializing format. The idea is to allow support for other protocols like GRPC, HTTP/1.l1(REST) with other data serialization formats like JSON.

Is there any workaround?
NA

What is the impact?

Upstream services can ingest data into Raccoon using various transport protocols which makes it easier to adopt.

Which version was this found?

NA

Solution

Use the existing server that exposes WebSocket endpoint and add an additional support for POST Method to allow HTTP/1.1 support. We can use the same API to support various serialization formats like JSON/protobufs based on Content-Type header.
GRPC can be served by another server on a different port.
