Ulid

Acest proiect este o implementare a standardului ULID în limbajul de programare Go. Oferă instrumente pentru generarea de identificatori unici universal, sortabili lexicografic, care combină timestamp-uri în milisecunde cu date aleatorii.

Biblioteca asigură că identificatorii mențin ordinea cronologică prin sortare alfabetică. Include un generator monoton pentru a garanta că mai mulți identificatori creați în aceeași milisecundă sunt produși într-o secvență strict crescătoare.

Proiectul acoperă generarea de identificatori unici și optimizarea cheilor primare în baze de date. De asemenea, oferă o interfață de linie de comandă pentru generarea de noi identificatori și extragerea informațiilor de timestamp din șirurile de identitate existente.

Features

ULID Implementations - Implements the ULID standard specifically for the Go programming language.
Lexicographical Sorting - Ensures identifiers are byte-sorted lexicographically, allowing them to be sorted alphabetically by creation time.
Monotonic Identifier Generation - Guarantees that identifiers generated within the same millisecond are produced in a strictly increasing sequence.
Unique Identifier Generators - Provides utilities for creating compact and unique strings combining timestamps and randomness for use as primary keys.
Entropy-Based Collision Prevention - Combines random entropy with timestamps to ensure global uniqueness and prevent collisions during high-frequency generation.
Millisecond Clock Sequences - Implements sequence numbers that reset per millisecond to maintain strict chronological order for identifiers.
Distributed Primary Key Generation - Provides time-ordered unique identifiers designed to optimize indexing and reduce fragmentation in database primary keys.
Crockford Base32 Encodings - Provides a case-insensitive, human-readable Base32 encoding that excludes ambiguous characters for easier data entry.
Identifier Bit-Packing - Implements techniques for packing timestamps and random data into a structured unique identifier using bitwise shifts.
Unique Identifiers - Implementation of Universally Unique Lexicographically Sortable Identifiers.
Unique ID Generation - ULID implementation.

Snowflake is a distributed unique ID generation service designed to produce non-colliding, time-ordered identification numbers at high scale. It functions as a scalable ID issuer that creates distinct entity identifiers across multiple server nodes to avoid coordination bottlenecks. The system utilizes stateless identifier coordination, calculating unique IDs through a deterministic mathematical formula rather than relying on a central database to track the last issued number. This approach allows it to generate identifiers for distributed database primary keys and high-scale transaction trac
