High Availability
ZooKeeper is designed to be highly available, with built-in redundancy and failover mechanisms that ensure minimal downtime.
Consistency
It follows a strict consistency model, ensuring that reads reflect the most recent writes, which is crucial for coordination and configuration management.
Scalability
ZooKeeper can handle a high number of read operations and can be scaled horizontally by adding more nodes to the ensemble.
Leader Election
ZooKeeper simplifies the implementation of leader election processes, making it easier to design fault-tolerant distributed systems.
Cluster Management
It aids in cluster management by providing mechanisms to track the status and configuration of nodes across a distributed system.
Watch Mechanism
ZooKeeper provides a watch mechanism that allows clients to be notified of data changes, helping to keep state synchronized across systems.
Yes, Apache ZooKeeper is considered a good choice for scenarios involving distributed system coordination, thanks to its proven track record, robust performance, and active community support.
We have collected here some useful links to help you find out if Apache ZooKeeper is good.
Check the traffic stats of Apache ZooKeeper on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Apache ZooKeeper on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Apache ZooKeeper's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Apache ZooKeeper on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

Next, Kafka requires Zookeeper and a broker. Instead of installing them manually, we use Docker Compose with this YAML file. - Source: dev.to / 3 months ago
Zookeeper is a distributed coordination service used in older versions of Kafka to manage cluster metadata, leader election, and configuration. It ensures consistency and synchronization across Kafka brokers. - Source: dev.to / over 1 year ago
Using a service discovery mechanism: A service discovery mechanism, such as etcd or ZooKeeper, can help to manage the complexity of microservices by providing a centralized registry of available services and their instances. - Source: dev.to / over 1 year ago
Apache ZooKeeper: A centralized service to generate unique IDs and prevent race conditions between instances. - Source: dev.to / over 1 year ago
To use Kafka, we also need to deploy a service that keeps configuration informations such as Zookeeper. - Source: dev.to / over 2 years ago
Failure Detection and Recovery It’s not enough to have backup systems. It’s also crucial to detect failures quickly. Modern systems employ monitoring tools and rely on distributed coordination systems such as Zookeeper or etcd to identify faults in real-time: once detected, recovery mechanisms are triggered to restore the service. - Source: dev.to / over 2 years ago
Zookeeper: is (was?) used for secrets management. It was also used as a basic health check, but has been since been replaced. Source: about 3 years ago
You can install Kafka from https://kafka.apache.org/quickstart. Because Druid and Kafka both use Apache Zookeeper, I opted to use the Zookeeper deployment that comes with Druid, so didn’t start it with Kafka. Once running, I created two topics for me to post the data into, and for Druid to ingest from:. - Source: dev.to / over 3 years ago
Please note that we use Zookeeper as the Governance Center. - Source: dev.to / over 3 years ago
Next, review deployment complexity such as DB-less versus database-backed deployments. For example, Kong does require running Cassandra or Postgres. Apigee requires Cassandra, Zookeeper, and Postgres to run, while other solutions like Express Gateway and Tyk only require Redis. Apache APISIX uses etcd as its data store, it stores and manages routing-related and plugin-related configurations in etcd in the Data... - Source: dev.to / over 3 years ago
ZooKeeper, a system for coordinating distributed nodes, similar to Google's Chubby. - Source: dev.to / over 3 years ago
ElasticJob achieves distributed coordination through ZooKeeper. In practical scenarios, users may start multiple jobs in the same project simultaneously, all of which use the same Apache Curator client. There are certain risks due to the nature of ZooKeeper and the callback method of Curator in a single event thread. - Source: dev.to / over 3 years ago
For now we just need to know that Kafka will be running n brokers acting as a cluster. The Kafka cluster will use Zookeeper to orchestrate the brokers. - Source: dev.to / over 3 years ago
We spin up a Zookeeper instance at port 2181 internally within the Docker network (i.e. Not accessible from the host). - Source: dev.to / over 3 years ago
To solve this issue we can use a distributed system manager such as Zookeeper which can provide distributed synchronization. Zookeeper can maintain multiple ranges for our servers. - Source: dev.to / over 3 years ago
Support the deployment of the ZooKeeper cluster through Bitnami. - Source: dev.to / almost 4 years ago
First, let's configure our Apache Zookeeper. Install desired Java version according to the official documentation. At the time of writing, the latest Zookeeper and Solr - both needs Java 11. - Source: dev.to / almost 4 years ago
2.Deploy Apache ShardingSphere-Proxy 5.1.2 and Apache ZooKeeper. ZooKeeper acts as a governance center and stores ShardingSphere metadata information. - Source: dev.to / almost 4 years ago
Currently, the deployment of Apache ShardingSphere-Proxy depends on the registry, and the deployment of the ZooKeeper cluster is also supported in the Apache ShardingSphere-Proxy chart. - Source: dev.to / almost 4 years ago
+1 for RAFT, Paxos is quite complex and easy to mess up. If you're lazy, you can just throw Zookeeper at the problem (this is what many Big Data systems like Spark and Kafka often use for synchronization and consensus): - https://zookeeper.apache.org/ - https://zookeeper.apache.org/doc/current/zookeeperInternals.html. - Source: Hacker News / almost 4 years ago
To work with Kafka, it is necessary to install Java. Because Kafka is a Scala and Java application also, installing Zookeeper will be required. - Source: dev.to / almost 4 years ago
