To help maintainers understand the design of the system, document the architecture of the Metrics Platform system. If I remember correctly, Santi has a working Google Doc that contains a lot of good content that could be used for this.
To do:
- Create Metrics Platform/Architecture
- Summarize the components of the system and their responsibilities
- Add a system diagram
- Add a link to the page under https://wikitech.wikimedia.org/wiki/Metrics_Platform#Metrics_Platform_maintainer_documentation
