ClickHouse supports multi-master asynchronous replication and can be deployed across multiple datacenters. Downtime of a single node or the whole datacenter won't affect the system's availability for both reads and writes.

ClickHouse scales well both vertically and horizontally. ClickHouse is easily adaptable to perform either on cluster with hundreds of nodes, or on a single server or even on a tiny virtual machine.

ClickHouse uses all available hardware to its full potential to process each query as fast as possible. It processes hundreds of millions to more than a billion rows and tens of gigabytes of data per single server per second.
