Snowflake

Snowflake is a HTTP server for generating unique ID numbers.

This is a Golang implementation of Twitter's Snowflake.

Spec

ID number is composed of:

• time - 41 bits (millisecond precision w/ a custom epoch gives us 69 years)
• configured machine id - 10 bits - gives us up to 1024 machines
• sequence number - 12 bits - rolls over every 4096 per machine (with protection to avoid rollover in the same ms)

This is equal to Twitter's Snowflake.
