Using Elasticsearch with FastAPI

FastAPI (https://fastapi.tiangolo.com/) is a new Python web framework based on asyncio (https://docs.python.org/3/library/asyncio.html) and Starlette (https://www.starlette.io/) that's powerful and enjoyable to use. The following features make FastAPI worth trying:

• FastAPI is one of the fastest Python web frameworks (https://www.techempower.com/benchmarks/#section=data-r20&hw=ph&test=query&l=yykm7z-cn&a=2).
• It has detailed and easy-to-use developer docs that can be found at https://fastapi.tiangolo.com/tutorial/.
• It creates an OpenAPI interface by default.
• You can type hint your code and get free data validation and conversion.
• You can create plugins easily using dependency injection.

Due to its async nature, FastAPI is very easy to integrate with AsyncElasicsearch.
