PyTram

PyTram é um framework Python para orquestração de Sagas assíncronas, inspirado no Eventuate Tram. Ele foi criado para facilitar a coordenação de transações distribuídas em sistemas baseados em microsserviços.


✨ Recursos

  • Orquestração de Sagas com múltiplos passos
  • Suporte a comandos e compensações
  • Adaptador para RabbitMQ (via aio-pika)
  • Repositório de Sagas em memória
  • Suporte a tolerância a falhas via pyfaulttolerance
  • Totalmente assíncrono e extensível

📦 Instalação

Você pode instalar via PyPI:

pip install pytram-saga

🚀 Exemplo de Uso

from pytram.saga.step import SagaStep
from pytram.saga.orchestrator import SagaOrchestrator
from pytram.persistence.memory import InMemorySagaRepository
from pytram.messaging.rabbitmq import RabbitMQAdapter

async def main():
    broker = RabbitMQAdapter("amqp://user:pass@host/vhost")
    await broker.connect()

    steps = [
        SagaStep(command="step1"),
        SagaStep(command="step2", compensation="compensate_step2"),
        SagaStep(command="step3")
    ]

    repo = InMemorySagaRepository()

    orchestrator = SagaOrchestrator("MySaga", steps, broker, repo)

    await orchestrator.start("saga-001", {"user_id": 42, "amount": 100.0})
