In a ZooKeeper engine, a znode is a node used to store and manage data. Znodes are organized into a hierarchical tree structure that is similar to the directory structure of a file system. Each znode has a unique path identifier. The ZooKeeper engine coordinates and manages distributed applications by maintaining znodes and provides features such as service synchronization and configuration management.
