title: Are there any side effects of setting config.cache_store?
body: <p>Ruby on Rails offers different caching techniques (<a href="https://guides.rubyonrails.org/caching_with_rails.html" rel="nofollow noreferrer">https://guides.rubyonrails.org/caching_with_rails.html</a>)</p>
  <p>I just want to save and fetch some data to Memcached. And I don't want to use Memcached for other types of Rails caching like page caching or SQL caching.</p>
  <p>I added the next settings to the environment file:
  <code>config.cache_store = :dalli_store</code>.
  And now get worked <code>Rails.cache.write</code> and <code>Rails.cache.read</code>. That's all of I need for my task.</p>
  <p>Can I be sure that Rails will not use :dalli_store storage for other internal mechanisms like SQL Caching.</p>
