updateCatalog
The updateCatalog command updates the namespace metadata in
the catalog. If you have a large federated database instance store,
it might take a while to update the catalog.

db.runCommand({ "updateCatalog" : 1, "stores": ["<storeName>",...], "background" : true })

The command returns the following output:
{ "ok" : 1 }
