Datastream helps you replicate historical data and ongoing changes
from operational databases and SaaS applications into your destination for
analytics and data synchronization. You can stream data from MySQL, Oracle,
PostgreSQL, SQL Server, MongoDB, and Spanner databases. Depending on
the database, supported deployments include on-premises hosts, self-managed
virtual machines, and managed services such as Cloud SQL, AlloyDB for PostgreSQL,
and Amazon RDS.

You can also replicate data from Salesforce and from

including Microsoft Dataverse, Salesforce Marketing Cloud, ServiceNow, and
Workday.
