Why I Over-Engineered a ULID Library for .NET

Unique identifiers are often treated as an afterthought, but for senior engineers and architects, they represent a critical choice in system design. "Good enough" identifiers are a ticking time bomb of index fragmentation and degraded performance. Why ULID over UUIDv7? While UUIDv7 is a step forward, its specification makes monotonicity optional. During high-concurrency bursts, many generators sacrifice order to stay fast. ByteAether.Ulid refuses this compromise. By mandating strict lexicographical sortability, it ensures your database indexes remain optimized and sequential. Solving the Overflow Problem A common failure point in ULID implementations is the 80-bit random component overflow. High-volume systems can easily exhaust the random space within a single millisecond, causing standard libraries to throw an OverflowException. ByteAether.Ulid handles this by automatically incrementing the timestamp component. This ensures unique, sorted IDs continue to generate even under extreme l
