Instaclustr Announces Customer-Initiated Resize For Kafka and Elasticsearch

By Instaclustr

Instaclustr, delivering reliability at scale through fully managed open source data technologies, today announced the release of any-to-any resizing for Kafka and Elasticsearch clusters on the Instaclustr Managed Platform.

Releasing this new functionality allows customers to dynamically resize their clusters without help from the Instaclustr Support team, providing customers a quicker resolution time.

There are a number of common scenarios when you may wish to resize your cluster. For example, prior to a known usage spike, you can resize to a larger instance size. Another common scenario would be increasing the node size as a result of growth in usage of the cluster when data storage or compute power is no longer adequate.

This new feature allows Instaclustr customers to manage cluster resizing without assistance from Instaclustr Support in a safe manner, and without data loss or downtime. The customer can simply select their cluster to resize and select the new size. The customer will then be provided with progress updates while the resizing process takes place. This functionality is common to the Console and Provisioning API. The customer-initiated resize functionality builds upon the existing resize capability available for Cassandra clusters. The full suite of customer-initiated resize options will be rolled out for Cassandra customers in the coming months.

“Instaclustr has years of operational experience conducting resize operations for our customers. We’re pleased to add further value for our customers by automating this process going forward. Customers can now get a fully automated yet tailored resize of their Kafka or Elasticsearch clusters while maintaining cluster reliability throughout the entire process.”

Ben Slater, Instaclustr Chief Product Officer.

The customer-initiated resize functionality offers the following key technical features:

  • Supported on Instaclustr Apache Kafka and Elasticsearch managed offerings
  • Supported across Provisioning API and Console. Support for the Terraform Provider will be provided in a subsequent release.
  • Available initially on AWS, with GCP and Azure cloud service providers to follow
  • Supports increases of disk, change of instance sizes, and change of both disk and instance for supported instance types only
  • No intervention required from Instaclustr Support when initiated by the customer
  • Safety checks are conducted as a prerequisite to the resize operation
  • The Instaclustr provisioning system chooses the most efficient path to execute the resize
  • Full documentation for customers on support portal

Log onto the Instaclustr console and spin up a cluster to take the resize functionality for a test drive.
