dflake 1.0.2

dflake

Snowflake ID implementation for the D language, for generating increasing, unique ids, without the need for synchronization of distributed systems.

import dflake;
auto gen = SnowflakeGenerator(123);
long id = gen.nextId();

Performance

Each individual generator can produce ids in a sequential, thread-safe manner. You can clone this project and run dub test to run the test suite which includes some performance tests.

On my machine (AMD Ryzen Threadripper 2920X 12-Core Processor), I have benchmarked it at generating slightly more than 4,000,000 ids per second.

Inspired by a Java implementation by callicoder.
