 Description   

The FCV 4.4 checkShardVersion protocol is, when the shard does not have a shardVersion cached for a namespace:

  • if the namespace is a collection, the shard returns StaleShardVersion
  • if the namespace is a view, the shard executes the request
    • the request will either return a view definition or CommandNotSupportedOnView
  • if the namespace does not exist, the shard executes the request
    • the request will either return empty results or NamespaceNotFound
