pysnowflake is a Python implementation of Twitter's snowflake service - https://github.com/twitter/snowflake
This is based on the pysnowflak python trift service that Erans did - https://github.com/erans/pysnowflake
Our use case wasn't thrift oriented but HTTP based, so this is a service that runs under the Tornado web framework. Which makes it possible to only have one depenancy (tornado).
Due to various reasons this implementation does not reach the performance indicated in the original Snowflake implementation, however it is good enough in most cases and can be combined with the help of a software load balancer such as HAProxy to run multiple processes to get higher performance.
- Install Tornado
- Run the service
usage: pysnowflake.py [--debug] [--port=9000] [--datacenter=DC_ID] [--worker=WORKER_ID]
Python based Snowflake server over HTTP
See the original snowflake server docs for a detailed description, but the bottom line is unique numbers will insure unique identifers generated. WORKER_ID is the identifier for this process DATACENTER_ID is the identifier for this datacenter
/id/<USERAGENT> -- get a unique ID, <USERAGENT> is provided for metrics purposes
/timestamp/ -- get the current timestamp for this host
/datacenter/ -- get the data center identifier for this process
/worker/ -- get the data center identifier for this process
