Shared-Nothing Architecture 

CrateDB is a distributed system that is built with a shared-nothing architecture. Every node is “equal” and can take over every task within the cluster. There is no hierarchy or various preferences when considering the nodes in the system. The fact that all nodes can perform any task provides built-in load-balancing as most clients support multiple connections to multiple hosts.

  • Scaling becomes easier.
  • No single point of failure. See High Availability to learn more.
  • Shards are automatically rebalanced across the different nodes.
