Millas
Millas is a simple cache mechanism. In this mechanism, cached values are dispersed and layered in time.
By the way, Millas is a magic cake which becomes 3 layers when baked once. And it is traditional sweets in Landes (France).
Mechanism
Dispersed cache
Cached values whose key is appended random and specified number to the end.
Layered in time
Expiration time of cached values is Layered.
Usage
It is not conscious of Milas.
cache = ActiveSupport::Cache::DalliStore.new
cache.write('millas', 'cake', expires_in: 1.minutes)
# Cache write: millas-1 ({:expires_in=>60 seconds})
# Cache write: millas-2 ({:expires_in=>120 seconds})
# Cache write: millas-3 ({:expires_in=>180 seconds})
=> 90916417477541888
cache.read('millas')
# Cache read: millas-2
=> "cake"
cache.exist?('millas')
# Cache exist: millas-1
=> true
cache.delete('millas')
# Cache delete: millas-1
# Cache delete: millas-2
# Cache delete: millas-3
=> trueInstallation
Add this line to your application's Gemfile:
gem 'millas'Or install it yourself as:
$ gem install millasConfiguration
Millas.configure do |config|
config.dispersion_number = 5 # default
config.perform_dispersing = true # default
config.second_intervals = 60 # default
endIf this mechanism is adopted only for a specific part, it should do as follows.
Millas.config.perform_dispersing = false
cache.write('millas', 'cake', expires_in: 1.minutes)
# Cache write: millas ({:expires_in=>60 seconds})
=> 883549951894749184
cache.write('millas', 'cake', expires_in: 1.minutes, dispersed: true)
# Cache write: millas-1 ({:expires_in=>60 seconds})
# Cache write: millas-2 ({:expires_in=>120 seconds})
# Cache write: millas-3 ({:expires_in=>180 seconds})
