64 bit sequential ID generator based on twitter snowflake ID generation algorythm

javasnowflake

Java implementation of twitter snowflake. 64 bit sequential ID generator based on twitter snowflake ID generation algorithm. id 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).
