How ZooKeeper Generates Sequence Numbers

In ZooKeeper, the Seq number is generated through a global counter in the ZooKeeper server. Whenever a new ZooKeeper node (znode) is created, the global counter increments by 1 and assigns that value as the Seq number for that node. This ensures that each znode has a unique Seq number and is incremented in the order it was created. The generation of Seq numbers is an atomic operation, ensuring both uniqueness and order.
