Configuration Changes in Elasticsearch

Elasticsearch uses circuit breakers to prevent its nodes from running out of JVM memory. If Elasticsearch estimates that an operation in progress will exceed the set circuit breaker limits, it stops the operation and returns an error. Hevo catches some of the exceptions thrown by Elasticsearch and recommends corrective actions. This document lists some of the exceptions and the recommended changes to your Elasticsearch settings.

Updating the configuration settings

You can configure and update the settings on a running cluster in your Generic Elasticsearch instance using the cluster update settings API. You can also modify the settings on an unstarted or shut down node using the Elasticsearch configuration file, elasticsearch.yml.

To make any configuration changes to your AWS Elasticsearch instance, you need to contact Hevo Support.
