An Experimental Comparison of Complex Objects Implementations in Big Data Systems
… language, often Java. Document databases such as MongoDB make use of hierarchical interchange formats--most popularly JSON--which embody a data model where individual records can themselves contain sets of records. Systems such as Dremel and AsterixDB allow complex nesting of data structures. The …
