Cache

Avo uses the application's cache system to enhance performance. The cache system is especially beneficial when dealing with resource index tables and license requests.

Cache store selection

The cache system dynamically selects the appropriate cache store based on the application's environment:

Production

In production, if the existing cache store is one of the following: ActiveSupport::Cache::MemoryStore or ActiveSupport::Cache::NullStore it will use the default :file_store with a cache path of tmp/cache. Otherwise, the existing cache store Rails.cache will be used.

Test

In testing, it directly uses the Rails.cache store.

Development and other environments

In all other environments the :memory_store is used.

Custom selection

There is the possibility to force the usage of a custom cache store into Avo.

# config/initializers/avo.rb
config.cache_store = -> {
  ActiveSupport::Cache.lookup_store(:solid_cache_store)
}

# or

config.cache_store = ActiveSupport::Cache.lookup_store(:solid_cache_store)

cache_store configuration option is expecting a cache store object, the lambda syntax can be useful if different stores are desired on different environments.

MemoryStore in production

Our computed system do not use MemoryStore in production because it will not be shared between multiple processes (when using Puma).

Solid Cache

Avo seamlessly integrates with Solid Cache. To setup Solid Cache follow these essential steps

Add this line to your application's Gemfile:

gem "solid_cache"

And then execute:

$ bundle

Or install it yourself as:

$ gem install solid_cache

Add the migration to your app:

$ bin/rails solid_cache:install:migrations

Then run it:

$ bin/rails db:migrate

To set Solid Cache as your Rails cache, you should add this to your environment config:

config.cache_store = :solid_cache_store
