High Speed and Scalability

CrateDB offers high speed and high scalability thanks to a truly distributed architecture, which allows to serve both massive ingest loads and hyper-fast reading performance. It can handle large volumes of data from different sources and offer automatic data rebalancing across the nodes thanks to a unique shared-nothing architecture. As business demands grow, so do data volumes and hardware requirements over time. When there is an increase in requirements for CPU, RAM, and Disk Storage/IOPS, additional nodes can be seamlessly added to the CrateDB cluster without manual intervention. The cluster automatically rebalances the data to accommodate the new nodes.

CrateDB is scalable from one to hundreds of nodes and can handle huge volumes of information. Its high-performance capabilities ensure query response time in milliseconds, which leads to efficient processing and analysis of data, providing real-time insights and responsiveness. This scalability and performance is maintained even as new nodes are added, making it an ideal solution for businesses experiencing growth.

The diagram below illustrates the automatic redistribution process:

1. The initial three node cluster utilizes about 70% of the available storage space.
2. The addition of a new node results in an unbalanced distribution of data.
3. The automatic redistribution of data initiates, until an almost equal level of storage consumption across the four nodes is achieved again.
