AMQP Index Queue for sunspot

Asynchronously index your sunspot models.

Rationale and influences

This library is heavily influenced by https://github.com/bdurand/sunspot_index_queue gem. My motivation to write a separate library instead of an adapter was mainly to remove features that were difficult to implement in an AMQP queue terms (keeping failed jobs and error messages, priorities). However, one "weird" feature, namely, retrying jobs after a certain period on failure, made its way through.

Installation

Add this line to your application's Gemfile:

gem 'sunspot_amqp_index_queue'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sunspot_amqp_index_queue

Usage

There are two parts to asynchronous indexer, first is a proxy that sends all index/remove requests to a queue:

# Somewhere in an initializer (for Rails) / before your code starts
require 'sunspot_amqp_index_queue'
amqp_config = {
  "host"       => "localhost",
  "port"       => 5672,
  "user"       => "guest",
  "pass"       => "guest",
  "vhost"      => "/",
  "queue_name" => "indexer_queue"
}
# Implies that Sunspot.session is already initialized as your real sunspot
# session
Sunspot.session = Sunspot::AmqpIndexQueue::SessionProxy.new(Sunspot.session, amqp_config)

Second part is an indexing daemon that handles processing. It boils down to

# ... require environment

loop do
  Sunspot.session.client.process(20) # process 20 entries
  sleep(1)
end

Thread-safety

It is safe to use a threaded solution for an indexer, separate connection to AMQP broker will be made per-thread. It is also safe to instantiate more than one Sunspot::AmqpIndexQueue::SessionProxy or Sunspot::AmqpIndexQueue::Client in one thread.
