Transport Features

The Transport layer of the client, OpenSearch::Transport, provides the following features:

• Pluggable logging and tracing
• Pluggable connection selection strategies (round-robin, random, custom)
• Pluggable transport implementation, customizable and extendable
• Pluggable serializer implementation
• Request retries and dead connections handling
• Node reloading (based on cluster state) on errors or on demand

For optimal performance, use a HTTP library which supports persistent ("keep-alive") connections, such as Patron or Typhoeus. Most such HTTP libraries are used through the Faraday HTTP library and its adapters.

Include the library's gem and adapter gem, and require the library and adapter in your code, and it will be automatically used. If you don't use Bundler, you may need to require the library explicitly (like require 'faraday/patron').

Currently these libraries will be automatically detected and used:

• Patron through faraday-patron
• Typhoeus through faraday-typhoeus for Faraday 2 or higher, or Faraday's built-in adapter for Faraday 1.
• HTTPClient through faraday-httpclient
• Net::HTTP::Persistent through faraday-net_http_persistent

Note on Typhoeus: You need to use v1.4.0 or up since older versions are not compatible with Faraday 1.0 or higher.

Note on Faraday: If you use Faraday 2.0 or higher, if the adapter is in a separate gem, you will likely need to declare that gem as well. Only the Net::HTTP adapter gem is included by default. Faraday 1.x includes most common adapter gems already.

DSL Features

The opensearch-dsl library provides a Ruby API for the OpenSearch Query DSL.

The library allows to programatically build complex search definitions for OpenSearch in Ruby, which are translated to Hashes, and ultimately, JSON, the language of OpenSearch.

All OpenSearch DSL features are supported, namely:

• Queries and Filter context
• Aggregations
• Suggestions
• Sorting
• Pagination
• Options
