Griddb - High performance, High scalability and High reliability database for big data

GridDB is an In-Memory NoSQL Database for highly scalable IoT applications . It has a KVS (Key-Value Store)-type data model that is suitable for sensor data stored in a timeseries. It is a database that can be easily scaled-out according to the number of sensors. High Reliability It is equipped with a structure to spread out the replication of key value data among fellow nodes so that in the event of a node failure, automatic failover can be carried out in a matter of seconds by using the replication function of other nodes.

GridDB utilizes a “Memory first, Storage second” structure. “Hot” data is kept in-memory, allowing for much faster writes/reads on the most-used data.
