* second level, in each project-collection, there is a Firebase document for each Feature Table
* third level, in the document for the Feature Table, there is a subcollection called `values` that contain a document per feature row. That document contains the following fields:
* `key` contains entity key as serialized `feast.types.EntityKey` proto
* `value` contains value as serialized `feast.types.Value` proto
* `values` contains feature name to value map, values serialized as `feast.types.Value` proto
* `event_ts` contains event timestamp (in the native firestore timestamp format)
* `created_ts` contains write timestamp (in the native firestore timestamp format)
