-In the context of a distributed Data Warehouse for ClickHouse® cluster, a node refers to an individual instance that stores and processes a portion of the data. Each node participates in data distribution, query execution, and replication to ensure balanced load, fault tolerance, and high availability. Nodes communicate with each other to coordinate tasks, execute queries in parallel, and maintain synchronized data replicas. They are configured with specific settings to define their roles and manage resources, allowing the cluster to scale and perform efficiently.
