Plugins extend the core functionality of Elasticsearch. There are many suitable plugins, including:
- The discovery plugins, such as the cloud AWS plugin that allows discovering nodes on EC2 instances
- The analysis plugins, to provide analyzers targeted at languages other than English
- The 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 you just have to add them to your cluster.
There are two ways to add plugins to a cluster in Elasticsearch Add-On for Heroku:
- Select one of the official plugins already available in Elasticsearch Add-On for Heroku.
- Upload a custom plugin and then install it on your cluster.
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 and Platinum subscriptions. For more information, see Uploading Custom Plugins, Dictionaries, and Scripts.
