MongoDB documentation model supports various data structure storage: Time-series, Geo, Text and Binary, etc. Schema free provides fast support to new model. Scale-out, automatic sharding, transparent to application. Able to support massive number of sensors without any application modification.
- Different/New generation products bring different sensor, create new data and function requirement, relational data is difficult to be merged, and iterate the data model.
- The number of sensor explosively increases, leads to high data volume grows, only scale-up cannot meet the requirement.
