Plugins are a way to enhance the core Elasticsearch functionality in a custom manner. They range from adding custom mapping types, custom analyzers, native scripts, custom discovery and more.
Deprecated in 2.3.0.
Site plugins and mixed plugins are deprecated and will be removed in 5.0.0. Instead, site plugins should either be migrated to Kibana or should use a standalone web server.
There are three types of plugins:
- Java plugins
- These plugins contain only JAR files, and must be installed on every node in the cluster. After installation, each node must be restarted before the plugin becomes visible.
- Site plugins
- Mixed plugins
- [2.3.0] Deprecated in 2.3.0. Mixed plugins contain both JAR files and web content.
