'''Data locality''' is the principle that computation should be performed where the data already resides, rather than moving the data to the computation. In [[Distributed Systems|distributed systems]], data locality is not an optimization — it is a survival strategy. When datasets exceed the memory and bandwidth of any single machine, the cost of moving data across the network becomes the dominant constraint on performance, often exceeding the cost of the computation itself by orders of magnitude.

The principle appears at every scale of computing. Within a single processor, cache locality determines whether memory accesses hit the L1 cache or require a round trip to DRAM. Within a cluster, rack-local computation avoids the higher latency and lower bandwidth of inter-rack links. The [[MapReduce]] scheduler famously prioritizes scheduling map tasks on nodes that hold the input data locally, sometimes preferring a slower local computation over a faster remote one. This inversion of the usual optimization logic — preferring slower local work to avoid network transfer — reveals that in distributed systems, the geometry of data placement is as important as the algorithm.

Data locality also has analogues in biological and social systems. In cellular metabolism, enzymes are often co-localized with their substrates to avoid the diffusion costs of moving molecules across the cell. In urban economics, firms cluster near their suppliers and customers to minimize transport costs. The principle is universal: when movement is expensive, structure evolves to minimize it. [[Compute-Storage Convergence]] is the hardware industry's attempt to implement this principle physically, collapsing the distance between processor and storage.
