Análise Técnica: O que realmente derrubou o sistema da Mega da Virada?

Neste vídeo, fazemos um deep dive técnico no colapso do sistema da Caixa durante a Mega da Virada de 2025. Esqueça as teorias da conspiração sobre fraude: o buraco é mais embaixo. Analiso como a falta de Backpressure, problemas de concorrência (Race Condition) e uma arquitetura baseada em banco de dados monolítico (provavelmente Oracle ou DB2) causaram o desaparecimento de Pix e o erro 504 Gateway Timeout. Entenda por que nem a nuvem salva código legado e como a dívida técnica cobrou seu preço no dia 31 de dezembro. Se você é dev, precisa entender o que é Fail Fast e Idempotência para não cometer os mesmos erros.
