Openname-resolver is a highly scalable server for Openname System. It resolves opennames (usernames) to profile data. It is blockchain-agnostic (currently uses the Namecoin blockchain) and is primarily meant for scaling read-only calls to the underlying blockchain. For achieving high throughput openname-resolver loads the entire namespace into memcached and then keeps the in-memory copy consistent with the blockchain. Read-only calls never hit disk and their scalability is completely decoupled from the scalability properties of the underlying database.
Openname-resolver requires memcached:
sudo apt-get install memcached libmemcached-dev zlib1g-dev
sudo apt-get install python2.7-dev
Before installing pylibmc (listed in requirements.txt) install the above packages.
Install coinrpc:
pip install git+ssh://git@github.com/opennamesystem/coinrpc.git
For quick deployment:
pip install -r requirements.txt
./runserver
Warmup cache and then keep memcached in sync with the blockchain:
source tools/setup_env.sh
python -m tools.warmup_cache
mkdir log
python -m tools.sync_cache
To deploy on Heroku:
heroku create
heroku addons:add memcachedcloud
git push heroku masterExample API call:
