Copy-on-write (CoW or COW), sometimes referred to as implicit sharing[1] or shadowing,[2] is a resource-management technique used in computer programming to efficiently implement a "duplicate" or "copy" operation on modifiable resources.[3] If a resource is duplicated but not modified, it is not necessary to create a new resource; the resource can be shared between the copy and the original. Modifications must still create a copy, hence the technique: the copy operation is deferred to the first write. By sharing resources in this way, it is possible to significantly reduce the resource consumption of unmodified copies, while adding a small overhead to resource-modifying operations.
