Module: Mova::ReadStrategy::Eager

Defined in:
lib/mova/read_strategy/eager.rb

Overview

This strategy is more perfomant with a remote storage, where each read results in a network roundtrip. Even if your cache or database is located on localhost, reading from a socket is much more slower than reading from memory. Instead of making one read per locale/scope fallback, we get combination of all fallbacks and make one request to the storage.

Examples:

Instantiating a translator with eager strategy

dalli = ActiveSupport::Cache::DalliStore.new("localhost:11211")
translator = Mova::Translator.new(storage: dalli)
translator.extend Mova::ReadStrategy::Eager
