Infrastructure

CrateDB distributes both data and queries across multiple nodes, executing workloads in parallel for high performance and linear scalability. This distributed SQL engine ensures fast aggregation, filtering, and search, even on massive datasets.

Every node in CrateDB operates independently, with its own storage, compute, and memory. There’s no single point of failure or centralized coordinator. This design maximizes reliability and ensures that hardware or network failures affect only the affected node, not the entire cluster.

CrateDB continuously monitors the state of the cluster and automatically redistributes data when nodes are added, removed, or recovered. This self-balancing mechanism ensures optimal resource utilization and high performance with minimal administrative effort.

Replication and automatic failover protect your data and ensure continuous service. If a node goes down, another replica immediately takes over, keeping your analytics uninterrupted.

CrateDB scales seamlessly by adding new nodes, no sharding strategy or downtime required. Each node adds capacity and compute power, enabling predictable, linear growth as your data and queries expand.

Each CrateDB cluster is composed of multiple nodes that work together in a fully distributed fashion. Nodes handle data storage, indexing, replication, and query execution, ensuring that the system remains balanced and resilient under load.
