1 ZooKeeper: A Distributed Coordination Service for Distributed Applications

ZooKeeper is a distributed, open-source coordination service for distributed applications. It

exposes a simple set of primitives that distributed applications can build upon to implement

higher level services for synchronization, configuration maintenance, and groups and

naming. It is designed to be easy to program to, and uses a data model styled after the

familiar directory tree structure of file systems. It runs in Java and has bindings for both Java

and C.

Coordination services are notoriously hard to get right. They are especially prone to errors

such as race conditions and deadlock. The motivation behind ZooKeeper is to relieve

distributed applications the responsibility of implementing coordination services from

scratch.

1.1 Design Goals

ZooKeeper is simple. ZooKeeper allows distributed processes to coordinate with each other

through a shared hierarchal namespace which is organized similarly to a standard file system.

The name space consists of data registers - called znodes, in ZooKeeper parlance - and these

are similar to files and directories. Unlike a typical file system, which is designed for storage,

ZooKeeper data is kept in-memory, which means ZooKeeper can achieve high throughput

and low latency numbers.

The ZooKeeper implementation puts a premium on high performance, highly available,

strictly ordered access. The performance aspects of ZooKeeper means it can be used in large,

distributed systems. The reliability aspects keep it from being a single point of failure. The

strict ordering means that sophisticated synchronization primitives can be implemented at the

client.

ZooKeeper is replicated. Like the distributed processes it coordinates, ZooKeeper itself is

intended to be replicated over a sets of hosts called an ensemble.

The servers that make up the ZooKeeper service must all know about each other. They

maintain an in-memory image of state, along with a transaction logs and snapshots in a

persistent store. As long as a majority of the servers are available, the ZooKeeper service will

be available.

Clients connect to a single ZooKeeper server. The client maintains a TCP connection through

which it sends requests, gets responses, gets watch events, and sends heart beats. If the TCP

connection to the server breaks, the client will connect to a different server.

ZooKeeper is ordered. ZooKeeper stamps each update with a number that reflects the order

of all ZooKeeper transactions. Subsequent operations can use the order to implement higher-

level abstractions, such as synchronization primitives.

ZooKeeper is fast. It is especially fast in "read-dominant" workloads. ZooKeeper

applications run on thousands of machines, and it performs best where reads are more

common than writes, at ratios of around 10:1.

1.2 Data model and the hierarchical namespace

The name space provided by ZooKeeper is much like that of a standard file system. A name

is a sequence of path elements separated by a slash (/). Every node in ZooKeeper's name

space is identified by a path.

ZooKeeper's Hierarchical Namespace

1.3 Nodes and ephemeral nodes

Unlike standard file systems, each node in a ZooKeeper namespace can have data associated

with it as well as children. It is like having a file-system that allows a file to also be

a directory. (ZooKeeper was designed to store coordination data: status information,

configuration, location information, etc., so the data stored at each node is usually small, in

the byte to kilobyte range.) We use the term znode to make it clear that we are talking about

ZooKeeper data nodes.
