University project, integrates use of Tokyo Cabinet / Tyrant in a Ruby on Rails web application for posting and viewing events and locations. Includes TokyoRecord, a tiny wrapper around rufus-tokyo for accessing Tokyo Tyrant tables. Tyrant instances are managed with tyrantmanager.
The basic idea is to store some data which is written frequently in Tokyo Cabinet tables, as benchmarks show that it is much faster than ActiveRecord and MySQL. So there are three such tables: for storing page views, event presences and event highlights.
Install Tokyo Cabinet and Tokyo Tyrant. On Ubuntu, you usually need to install this library before that:
apt-get install libbz2-dev
Get the latest sources from the Tokyo website, unpack and do the
./configure && make && sudo make install thing.
Install all required gems:
sudo rake gems:install
Copy database.yml and adjust it to your MySQL setup:
cp config/database.yml.example config/database.yml
Starting the application
You may wish to generate some fake data:
There’s a script which will tell tyrantmanager to run all the Tyrant instances and boot Mongrel:
One of the Tyrant tables is called Highlights, for simulating the case of serving variable data on a homepage that gets a lot of views. You can populate it with random events with the following rake task:
Eventually you’ll see something like
To run the test suite, you need to manually run two Tyrant instances on expected ports:
ttserver -port 19851 page_views.tct ttserver -port 19861 presences.tct
