Nodecentric

Nodecentric is a term used in computing to describe an approach in which individual nodes are treated as the primary unit of computation, storage, and decision-making within a network or system. In a node-centric model, each node holds agency over its data and responsibilities, and interactions among nodes are often peer-to-peer rather than coordinated by a central controller.

In distributed systems and network design, node-centric architectures emphasize locality and autonomy. Decisions about routing, data replication, and processing can be made at or near the node that holds the relevant data. This can improve fault isolation and scalability, but may increase system complexity and require robust consistency mechanisms to coordinate state across nodes.

In graph processing and graph databases, node-centric concepts position nodes as first-class citizens. Computations focus on node properties and their local neighborhoods, with algorithms for centrality, clustering, and traversal operating primarily through node-centric steps rather than global edge-centric sweeps. This perspective can influence data modeling, indexing, and query planning.

In practical terms, node-centric patterns appear in edge computing, distributed file systems, and certain peer-to-peer or decentralized networks where nodes independently manage resources and state while cooperating to achieve global objectives. The term is sometimes used descriptively to contrast with host-centric, service-centric, or edge-centric paradigms.
