There are so many features I like but this feature is something I think people do not know about and it is a feature that will be very valuable for a multi-model database which I believe is the future.

JSON Data Guide allows JSON data to be saved as it is and to be used with SQL. In other words it gives the ability to be able to write without schema but read with schema which is a functionality we need in the world of Big Data.

JSON Data Guide can be either persistent or transient. There are two formats of JSON Data Guide: flat or hierarchical. The hierarchical format includes features like views on top of a set of JSON files and virtual columns.

JSON Data Guide enables FSDM (Flexible Schema Data Management) in a RDBMS. It allows saving data in its original format without missing the opportunity to use that data efficiently. And therefore it is one step closer to a multi-model database.
