Modern Flask
性能基准
以 gunicorn 为服务器，以 --workers 1 --threads 1 为性能基准

配置
Flask.config
使用环境变量 CONFIG_SOURCE 来判断配置来源，只支持 Python 类型
- 本地文件
xxxx.py
- Kubernetes 资源
kubernetes://[NAMESPACE]/configmaps/[NAME]/[KEY]kubernetes://[NAMESPACE]/secrets/[NAME]/[KEY]kubernetes://configmaps/[NAME]/[KEY]kubernetes://secrets/[NAME]/[KEY]
- HTTP 资源
http://xxxxx.xxxx/xxxx.pyhttps://xxxxx.xxxx/xxxx.py
默认为本地文件 config.py
可观测性
可观测性框架基于 OpenTelemetry，使用 Zipkin 作为导出格式
默认启用了对以下组件的观测
- logging
- flask
- sqlalchemy
- redis
可以使用 Flask.config 的 SERVICE_NAME 自定义 service.name
配置来源于标准环境变量，详细参考:
- https://opentelemetry-python.readthedocs.io/en/latest/exporter/zipkin/zipkin.html
- https://opentelemetry-python-contrib.readthedocs.io/en/latest/instrumentation/logging/logging.html
指标使用 Prometheus，暴露于 /metrics 路径下
