1.1. Every Node Can Store Data

Unlike a file system, every node in ZooKeeper can store data. In a file system, only file nodes can store data, while directory nodes cannot.

1.2. The Data Storage Limit of Each Node Is 1 MB

To ensure high throughput and low latency, ZooKeeper maintains this tree-shaped directory structure in memory. This characteristic means ZooKeeper cannot be used to store large amounts of data. The data storage limit of each node is 1 MB.
