SCRU128: Sortable, Clock and Random number-based Unique identifier
SCRU128 ID is a supersede UUID that has the following features:
- 128-bit unsigned integer type
- Sortable by generation time (as integer and as text)
- 25-digit case-insensitive textual representation (Base36)
- 48-bit millisecond Unix timestamp that ensures useful life until year 10889
- Up to 281 trillion time-ordered but unpredictable unique IDs per millisecond
- 80-bit three-layer randomness for global uniqueness
