DAGFS, or Directed Acyclic Graph File System, is a type of file system that utilizes a directed acyclic graph (DAG) structure to manage and organize data. Unlike traditional file systems that rely on hierarchical directory structures, DAGFS allows for more flexible data relationships, enabling efficient storage and retrieval of files. This approach can enhance performance in scenarios involving large datasets and complex data interdependencies, making it particularly useful in distributed computing and big data applications.
