## What it is
The repository for the second edition of Rinha de Backend, a Brazilian community backend performance challenge focused on concurrency control via a credit/debit transaction HTTP API. It provides the challenge specification, validation tests, and load-testing setup for participants to submit and benchmark their implementations.

## Use cases
- practice building a high-concurrency HTTP API
- benchmark my backend against others under load
- learn concurrency control and database locking strategies
- participate in a community backend coding challenge
- test how my stack handles race conditions on account balances
- find reference implementations of the rinha de backend challenge

## When to choose
- you want a fun, well-defined performance challenge with community results
- you want to stress-test concurrency handling in your language or framework of choice
- you want to study winning solutions for low-latency transactional APIs

## When to avoid
- you need production-ready backend code rather than a contest exercise
- you want a general-purpose load-testing tool rather than a fixed challenge spec
- the challenge deadline has passed and you only want an active competition

## Facets
- artifact type: learning-resource
- maturity: active
- function: benchmarking, load-testing, concurrency, http-server, api-framework
- domain: developer-tools, performance, backend, apis, testing
- platform: cross-platform, cli
- tags: backend-challenge, coding-competition, load-testing, concurrency-challenge, brazilian-community, http-api, pessimistic-locking, docker
