Epic Summary
Summary
Move tracking of views from the primary shard for a database, to the catalog, and make view definitions available on mongos
Motivation
The status quo, where views are tracked on the primary shard for their database, has a few downsides:
- View definitions require an extra round trip to resolve
- Query doesn't have access to the full universe of namespaces on routers
- Views living on the primary shard for a database necessitates the continued existence of primary shards for databases
Moving view definitions will solve those problems, improving performance, ability to perform query planning and removing a barrier to getting rid of the notion of primary shards (and in turn removing a barrier to removing the movePrimary command)
