Documentação do Datastream
O Datastream é um serviço de replicação de dados e captura de dados alterados (CDC) sem servidor e fácil de usar, que permite sincronizar dados de maneira confiável e com latência mínima.
O Datastream oferece replicação contínua de dados de bancos de dados operacionais para o BigQuery. Além disso, o Datastream oferece suporte à gravação do fluxo de eventos de alteração no
Cloud Storage e oferece integração simplificada com modelos do Dataflow para criar
fluxos de trabalho personalizados e carregar dados em uma ampla variedade de destinos, como Cloud SQL e
Spanner. Você também pode usar o Datastream para aproveitar o fluxo de eventos diretamente do
Cloud Storage e implementar arquiteturas orientadas a eventos. O Datastream oferece suporte a fontes Oracle, MySQL, SQL Server e PostgreSQL, incluindo AlloyDB para PostgreSQL e AlloyDB Omni.

In addition, Datastream supports writing the change event stream into\nCloud Storage, and offers streamlined integration with Dataflow templates to build\ncustom workflows for loading data into a wide range of destinations, such as Cloud SQL and\nSpanner. You can also use Datastream to leverage the event stream directly from\nCloud Storage to realize event-driven architectures.
