Evaluation of other framework options:

1. Flask + flask-smorest + Marshmallow + Gunicorn
   Stability: Flask (pypi 1.1.2; github 50k stars), flask-smorest (pypi 0.21.0; github 226 stars), Marshmallow (pypi 3.5.2; github 4.6k stars), Gunicorn (pypi 20.0.4; github 6.8k stars)
   Streaming: HTTP/1 chunked encoding requires support from mod_wsgi and Apache
   OpenAPI: Autogenerated by flask-smorest
   Documentation: Excellent. Includes useful example code. +Stack overflow
   Deployment: Gunicorn --> Flask/SCope

2. Quart + Hypercorn + quart-openapi + Databases
   Note: Using Marshmallow is not really mentioned. Very close to the Flask API
   Stability: Quart (pypi 0.11.5; gitlab 682 stars), Hypercorn (pypi 0.9.5; gitlab 151 stars), quart-openapi (pypi 1.5.3; github 57 stars), Databases (pypi 0.3.2; github 1.2k stars)
   Streaming: Yes (https://pgjones.gitlab.io/quart/how_to_guides/streaming_response.html) and server sent events
   OpenAPI: Yes though quart-openapi
   Documentation: Excellent. Includes useful example code. +Stack overflow
   Deployment: Hypercorn --> Quart

3. Sanic + sanic-restplus + Databases
   Note: sanic-restplus (based on flask-restplus) has no docs for Marshmallow or pydantic integration.
   Stability: Sanic (pypi 19.12.2; github 13.7k stars), sanic-restplus (pypi 0.5.3; github 89 stars), Databases (pypi 0.3.2; github 1.2k stars)
   Streaming: Both request and response
   OpenAPI: Yes through sanic-restplus
   Documentation: Very good. Includes useful example code. +Stackoverflow +Awesome Sanic
   Deployment: Sanic

4. FastAPI + Hypercorn + Databases
   Notes: Explicitly for APIs. No mention of Marshmallow. Validation with Pydantic built in. Example for msgpack response and consideration flatbuffer response when propper HTTP Accept header is provided.
   Stability: FastAPI (pypi 0.54.1; github 13.4k stars), Hypercorn (pypi 0.9.5; gitlab 151 stars), Databases (pypi 0.3.2; github 1.2k stars)
   Streaming: https://www.starlette.io/responses/#streamingresponse
   OpenAPI: Built-in auto-generation + JSON Schema (https://fastapi.tiangolo.com/features/#automatic-docs)
   Documentation: Excellent. Includes useful example code. +Stackoverflow
   Deployment: Hypercorn --> FastAPI
