Plugins extend the core functionality of Elasticsearch. There are many suitable plugins, including:
- Discovery plugins, such as the cloud AWS plugin that allows discovering nodes on EC2 instances.
- Analysis plugins, to provide analyzers targeted at languages other than English.
- Scripting plugins, to provide additional scripting languages.
Plugins can come from different sources: the official ones created or at least maintained by Elastic, community-sourced plugins from other users, and plugins that you provide. Some of the official plugins are always provided with our service, and can be enabled per deployment.
There are two ways to add plugins to a deployment in Elasticsearch Add-On for Heroku:
Custom plugins can include the official Elasticsearch plugins not provided with Elasticsearch Add-On for Heroku, any of the community-sourced plugins, or plugins that you write yourself. Uploading custom plugins is available only to Gold, Platinum, and Enterprise subscriptions. For more information, check Upload custom plugins and bundles.
To learn more about the official and community-sourced plugins, refer to Elasticsearch Plugins and Integrations.
Plugins are not supported for Kibana. To learn more, check Restrictions for Elasticsearch and Kibana plugins.
