SN Supun N. Analyst/Programmer Higher Education Enterprise (\> 1000 emp.) 7/19/2018 "Distributed coordination with Zookeeper" 4.5/5 What do you like best about ZooKeeper? Zookeeper is a single software component which can provide solutions for all the distributed coordination requirements ranging from leader election, service discovery, and distributed cache. Review collected by and hosted on G2.com. What do you dislike about ZooKeeper? Although Zookeeper can be used to solve almost all the distributed coordination requirements, it's APIs are very primitive and hence often requires more code to be written for getting a task done even for the standard tasks. But this can be overcome by using Zookeeper with Apache curator. Review collected by and hosted on G2.com. Recommendations to others considering ZooKeeper: Don't use Zookeeper APIs directly, but use it with Curator. This will make your life much easier. Review collected by and hosted on G2.com. What problems is ZooKeeper solving and how is that benefiting you? I have used Apache Zookeeper for handling the distributed coordination requirements in several distributed systems that I have developed. We choose Zookeeper because it is a mature opensource product which is wide used in industry. Review collected by and hosted on G2.com.

Associate Software Engineer Marketing and Advertising Small-Business (50 or fewer emp.) 7/18/2018 "Best Free Key Store Service for Distributed Systems" 5/5 What do you like best about ZooKeeper? Zookeeper is open source, tried and tested for many many years, so it has a lot of documentation, and has a very large amount of room for scaling. Review collected by and hosted on G2.com. What do you dislike about ZooKeeper? There is a bit of a learning curve to zookeeper, as managing znodes isn't the easiest thing to start with. We created a visual GUI to manage nodes at one point with Electron. Review collected by and hosted on G2.com. Recommendations to others considering ZooKeeper: While there is somewhat of a learning curve, the value gained from using it is uncanny. Review collected by and hosted on G2.com. What problems is ZooKeeper solving and how is that benefiting you? Zookeeper allows us to keep metadata distributed across systems so that we don't have a single point of failure.

Zookeeper provide us high performance coordination service for distributed applications. Zookeeper nodes store their data in hierarchical name space, like tree data structure. Various benefits of zookeeper are Ordered messages, simple distribution coordination process,synchorization, reliability Review collected by and hosted on G2.com. What do you dislike about ZooKeeper? If we want to do service discovery, other solutions like consul have it baked in, with health check in loops.limited support for cross cluster scenarios . Zookeeper may however help with scalability and perhaps cross data center Review collected by and hosted on G2.com. What problems is ZooKeeper solving and how is that benefiting you?

It is customizable, and once you get it up and running it really doesn't need supervision. Once we overcame the permissions issues with getting zookeeper to manage our nodes in a lab environment where we did not have root access, we did not have to touch zookeeper for the duration of our research project. It took care of our storm cluster, balancing workloads and restarting nodes who died without issue. Review collected by and hosted on G2.com. What do you dislike about ZooKeeper? It is difficult to use in an individual user environment. It requires a lot of integration done by someone with root permissions to get zookeeper to run in a lab clustered environment. Review collected by and hosted on G2.com. What problems is ZooKeeper solving and how is that benefiting you? We were using it as a cluster manager to manage Storm nodes for an undergraduate research project. Review collected by and hosted on G2.com.

You will need to maintain a pretty big stack. Review collected by and hosted on G2.com.

Though if you need more complex message structure you can look at solutions like RabbitMQ and Redis. Review collected by and hosted on G2.com. What problems is ZooKeeper solving and how is that benefiting you? We used Zookeeper along with Kafka, so Kafka requires it. But you can use it to coming between your nodes. As a heartbeat checker for example. Review collected by and hosted on G2.com.

ZooKeeper provides an infrastructure for cross-node synchronization and can be used by applications to ensure that tasks across the cluster are serialized or synchronized. Review collected by and hosted on G2.com. What do you dislike about ZooKeeper? 1.Adding New ZooKeeper Servers Can Lead to Data Loss 2.The ZooKeeper server cannot be migrated from version 3.4 to 3.3, then back to 3.4, without user intervention. Review collected by and hosted on G2.com. What problems is ZooKeeper solving and how is that benefiting you? Architecting a distributed system is not a trivial problem; it is very prone to race conditions, deadlocks, and inconsistency. Making cluster coordination fast and scalable is just as hard as making it reliable. That’s where Apache ZooKeeper, a coordination service that gives you the tools you need to write correct distributed applications, comes in handy. Review collected by and hosted on G2.com.
