## What it is
Tinyid is a distributed unique ID generator service built in Java, backed by MySQL, exposing a REST API and a high-performance Java client. It supports over 10 million QPS per instance via the client and allows configurable delta/remainder sequences for custom ID patterns.

## Use cases
- generate unique distributed ids for database primary keys
- get high-throughput sequential ids in a java microservice
- fetch ids over a rest api from non-java services
- generate odd or stepped id sequences like 1,3,5,7
- batch-generate multiple ids in one call

## When to choose
- you need globally unique numeric ids across multiple services or datacenters
- you want a self-hosted alternative to leaf/snowflake-style id services with mysql storage
- your java application needs millions of id generations per second

## When to avoid
- you only need single-instance auto-increment ids from your database
- you require string or uuid-style ids rather than numeric sequences
- you need an actively developed project with recent releases

## Facets
- artifact type: service
- maturity: maintenance
- function: api-framework, http-server, database
- domain: backend, microservices, developer-tools
- platform: jvm, self-hosted
- tags: id-generator, distributed-id, unique-ids, mysql, rest-api, java-client, web-server
