= Elasticsearch

Elasticsearch is the distributed, RESTful search and analytics engine at the
heart of the https://www.elastic.co/products[Elastic Stack]. You can use
Elasticsearch to store, search, and manage data for:

* Logs
* Metrics
* A search backend
* Application monitoring
* Endpoint security

\... and more!

To learn more about Elasticsearch's features and capabilities, see our

 * arbitrary Charset.

 * <p>This is an alternative to copying the data to an {@code OutputStream} via a {@code Writer},
 * which is necessarily blocking. By implementing an {@code InputStream} it allows consumers to
 * "pull" as much data as they can handle, which is more convenient when dealing with flow
 * controlled, async APIs.

Плюс к этому простой факт, что Python — основной язык для **Data Science**, Машинного обучения и особенно Глубокого обучения, делает FastAPI очень хорошим выбором для веб-API и приложений в области Data Science / Машинного обучения (среди многих других).
