Dedicated ZooKeeper for Apache Kafka®

Instaclustr is pleased to announce the release of dedicated Apache ZooKeeper nodes as an additional optional feature of our Managed Apache Kafka offering. Apache ZooKeeper is used for the management and coordination of nodes in Kafka.

Dedicated Kafka ZooKeeper nodes provide customer benefits in situations that require high performance and reliability:

  • Improvements to reliability in failure scenarios (primarily due to less chance of Apache ZooKeeper nodes and Kafka brokers failing simultaneously)
  • Apache ZooKeeper nodes can be scaled independently of Apache Kafka
  • Reduction in I/O conflict between ZooKeeper and Apache Kafka processes.

Key features of the dedicated open source Kafka ZooKeeper solution include:

  • Only available for Apache Kafka version 2.5.1 and above
  • Provides customers with the option to select dedicated ZooKeeper nodes in developer and production ready node sizes. The support page for this new feature outlines this process
  • Available on AWS, GCP, and Azure cloud service providers
  • Supports provisioning via the Instaclustr Console, Provisioning API, or via the Instaclustr Terraform provider
  • Access to Apache ZooKeeper specific monitoring metrics via our API or console
  • Continuous monitoring and alerting
  • 24×7 comprehensive support from our Technical Operations team

“In the event of a node failure, this architecture is great as we’re not faced with the potential loss of a Kafka Broker and ZooKeeper node at the same time. It’s far more robust, reducing recovery time, and reducing the risk of edge case issues with cluster state inconsistencies. More generally, having dedicated ZooKeeper eliminates contention for resources such as IO, allowing ZooKeeper to remain performant even as load increases on Kafka, reducing bottlenecks and latency.”—Joe Clay, Instaclustr Technical Operations.


With the introduction of dedicated ZooKeeper nodes, we have revised our SLAs. Deploying dedicated ZooKeeper moves Enterprise tier availability SLA from 99.99% to 99.999%. Instaclustr continues to offer industry leading availability SLAs. Full details can be found on our SLA page.

For existing customers interested in migrating to Dedicated ZooKeeper nodes, please contact our Support team to discuss your requirements.
