The Data Life-Cycle Lab Earth and Environment at KIT manages data from Earth-observing climate satellites such as Envisat MIPAS, which is stored in the NoSQL database MongoDB. The size of data in question makes it necessary for it to be distributed across a large database cluster, using sharding - a using horizontal-partitioning solution available in MongoDB.

The size of data in question makes it necessary for it to be distributed across a large database cluster, using sharding - a using horizontal-partitioning solution available in MongoDB.
