Current version 1.0.2
for example, I have a huge config for game server ".gspec/gequipment_strengthen.plist". It will delay my request if storing the data in redis and the stress of redis is high. It will consume large memory (480M) when storing the data by ruby hash object. So I made this gem. It's fast and it comsume 5M memory only.
{
'234234' => {'id' => '23232', 'name' => 'haha'},
'234235' => {'id' => '23235', 'name' => 'haha2', 'hp' => '232'}
'234236' => {'id' => '23235', 'name' => 'haha2', 'attack' => '2322'}
}
For example, loading a game config .gspecgequipment_strengthen.plist will use 480M when using ruby Hash like this:
{'234232' => {id: '23423', name: 'haha'}}
Because there are about 1440000 ruby String objects when loading to memory.
And it will use 5M when using SMatrix.
Result from test: rspec .gspecgperformance_spec.rb
Add this line to your application's Gemfile:
gem 's_matrix', '~>1.0'
And then execute:
$ bundle
Or install it yourself as:
$ gem install s_matrix
# example for rails, config/initializers/init_game_data.rb
# every thing will change to string (.to_s) when saving to SMatrix
# EQUIPMENTS = SMatrix.new
# load_your_equipments_excel.each do
EQUIPMENTS.add_row('10001', {'id' => '10001', 'name' => 'wood sword', 'attack' => '342'})
EQUIPMENTS.add_row('20002', {id: 10002, name: 'shoe', speed: 5})
# end
ROLES = SMatrix.new
# load_your_role_excel.each do
ROLES.add_row('30002', {id: 30002, name: 'Fighter', speed: 20})
# end
# everything get back will be string
EQUIPMENTS['10001'].should == {'id' => '10001', 'name' => 'wood sword', 'attack' => '342''}
EQUIPMENTS['10001']['id'].should == '10001'
EQUIPMENTS['20002'].should == {'id' => '10002', 'name' => 'shoe', 'speed' => '5'}
EQUIPMENTS['20002']['attack'].should be_nil
EQUIPMENTS.size.should == 2
# or you can use get_row instead of []
EQUIPMENTS.get_row('20002')
# each
EQUIPMENTS.each {|k, v| k == '10001', v == {'id' => '10001', 'name' => 'sword', ...} }
# all
EQUIPMENTS.all.should == { '20002' => {'id' => '10002', 'name' => 'shoe', 'speed' => '5'}, '20003' => {} }
# first
EQUIPMENTS.first.should == ['20002', {'id' => '10002', 'name' => 'shoe', 'speed' => '5'}]
# ids
EQUIPMENTS.ids.should == ['20002', '20003']
# keys
EQUIPMENTS.keys.should == ['id', 'name', 'hp']
# find -- find the first one
EQUIPMENTS.find({name: 'shoe'}).should == ['20002', {'id' => '10002', 'name' => 'shoe', 'speed' => '5'}]
# to_s for debug
