ShiroFlake

ShiroFlake is a distributed unique ID generator inspired by on Twitter's Snowflake

ShiroFlake by default using same parameter that used in Twitter's Snowflake.

A ShiroFlake ID is composed of

41 bits for time in units
12 bits for a machine id
10 bits for a sequence number

But you can set the unsigned parameter to true at initialization the generator to use full 64 bit.

var generator = new ShiroFlakeGenerator(
    1, // machine id
    unsigned: true);

As a result, ShiroFlake has the following advantages:

• The lifetime (~139 years if unsigned is true) is longer than that of Snowflake (69 years)
• It can work in more distributed machines (2^12) than Snowflake (2^10)
