UUID v7 Generator
Generate time-ordered, database-friendly UUID v7 strings in bulk.
Why UUID v7 is the Future of Database Primary Keys
Standard UUID v4 strings are completely random, causing severe indexing fragmentation (page splits) in databases like MySQL or PostgreSQL when used as primary keys. **UUID v7** incorporates Unix timestamp milliseconds into the first 48 bits, ensuring they remain chronologically ordered. This speeds up inserts and query lookups.
