Objective

Enable users to:

• export lighthouse results to the cloud
• query certain types of lighthouse results from the cloud (e.g. only sites X and Y with devtools-based throttling)
• visualize these lighthouse results locally

This will enable the lighthouse team to analyze both the accuracy (variance between various configs - WPT-based or DevTools-based network throttling) and precision (variance between runs with the same config)

Querying

Example queries:

• All results from 3/28 - 3/29 for sites X and Y for all types of configuration

Dimensions for querying:

• Date range (when it was run)
• Browser version
• CPU Throttling type
• Network Throttling type
• Sites
• Platform (real device or emulated) or an overall systems performance metric (Ops/second)

Data model (probably Cloud Datastore)
