MySQL forces rows to fit a schema, with some value for each column (including NULL), whereas MongoDB documents only force a document to have an _id field. TokuMX, TokuDB, and InnoDB cluster an index that can be thought of as a primary key, and use that primary key as a row identifier for secondary indexes.
