How do ZooKeeper clients communicate with the server?

The communication between ZooKeeper clients and servers is conducted over the TCP protocol. After establishing a connection, clients can send requests to the server and receive responses. Clients interact with the server by sending various types of requests such as creating nodes, reading nodes, and updating nodes. The server processes the client’s requests and returns the results.

The communication between ZooKeeper clients and servers is based on persistent connections, allowing for long-lasting communication between the two. This design of persistent connections reduces the overhead of establishing and disconnecting connections, thereby improving communication efficiency and performance.

In general, communication between the ZooKeeper client and server is based on a persistent TCP connection, allowing for interaction between the client and server through the exchange of requests and responses.
