Some of the Applications/Organizations Using Apache Curator






The originator of Curator, it is used heavily in the company for leader selection, locks, sequence generation, among many other things.




Making heaving use of Curator and some ported recipes in Clojure in our product, CxEngage


Currently powering feature flagging system as well as SOA infrastructure.


Built a locking solution that can give out locks at the rate of 10k locks per second. Uses Exhibitor to manage the ZK cluster.




Distributed and fault-tolerant realtime computation: stream processing, continuous computation, distributed RPC, and more.


Metamarkets Druid Data Store.

Fuse Fabric

Distributed configuration, management and provisioning service


Galaxy is a high-performance in-memory data-grid (IMDG) that can serve as a basis for building distributed applications that require fine-tuned control over data placement and/or custom distributed data-structures.

Apache Drill

Apache Drill provides low latency ad-hoc queries to many different data sources, including nested data. Inspired by Google's Dremel, Drill is designed to scale to 10,000 servers and query petabytes of data in seconds.

General Electric

Snowizard Discovery - A Dropwizard bundle that can be used to register a Dropwizard service into Zookeeper upon startup. Connectivity to Zookeeper is provided by Netflix's Curator library and its built in Service Discovery framework.

Apache Oozie

Apache Oozie is a scalable system for managing and scheduling workflows that run different types of Hadoop jobs (such as MapReduce, Pig, Hive and Sqoop) as well as system specific jobs (such as Java programs and shell scripts). It uses Curator’s service discovery and distributed locks for coordinating it’s active-active High Availability.

Apache Spark

Apache Spark is a fast and general engine for large-scale data processing. Uses Curator for leader elections, etc.
