Datastream is a serverless and easy-to-use change data capture (CDC) and replication
service that lets you synchronize data reliably, and with minimal latency.
Datastream provides seamless replication of data from operational databases into
BigQuery. In addition, Datastream supports writing the change event stream into
Cloud Storage, and offers streamlined integration with Dataflow templates to build
custom workflows for loading data into a wide range of destinations, such as Cloud SQL and
Spanner. You can also use Datastream to leverage the event stream directly from
Cloud Storage to realize event-driven architectures. Datastream supports Oracle, MySQL,
SQL Server, and PostgreSQL (including AlloyDB for PostgreSQL and AlloyDB Omni) sources.
