GridDB is a Key-Value Store (KVS) database built by Toshiba. It is designed to provide a versatile data store for large data generated by IoT devices, to facilitate gaining insights and generating values from IoT data.

History

Toshiba started development of GridDB in 2011. Its first commercial release is in 2013. The community version (CE) was open-sourced in 2016.

Data Model

Key/Value

The data model of GridDB is key-container which extends typical NoSQL Key-Value store. Containers consists of two types: Collection Container, a general-purpose container; and TimeSeries Container, for time series data.
