When testing Atlas Data Lake with the ruby driver, we are having issues with cursors, in particular getting the next batch. While mongod/mongos returns a cursor namespace that uses the originating database and collection names, Atlas Data Lake does not.
For example, issuing the query on the "test" database, db.foo.find(), mongod/mongos will return a cursor with the namespace "test.foo". However, Atlas Data Lake will return a namespace more like "cursors.lkajlkasdf-3980238d908sdf".
As such, any getMore requests on Atlas Data Lake will result in cursor not found messages. We've tested both find and aggregate.
