Google Cloud Datastream

Purpose: Datastream is a serverless change data capture and replication service for synchronizing data with minimal latency.
Replication modes: A stream can capture ongoing changes and backfill historical data from its source.
Serverless: Datastream requires no resources to provision or manage and scales up or down automatically.
Sources: Documented sources include Oracle, MySQL, PostgreSQL, AlloyDB, SQL Server, MongoDB, Spanner, Salesforce, ServiceNow, Workday, and Microsoft Dataverse, with some listed as preview.
Destinations: Supported destinations are BigQuery, Cloud Storage, and Apache Iceberg tables.
Integrations: Datastream integrates with Dataflow templates to load data from Cloud Storage into destinations including BigQuery, Cloud SQL, and Spanner.
Connectivity: Connectivity options include IP allowlisting, a forward SSH tunnel, and private connectivity over VPC peering.
Encryption: Buffered data is encrypted at rest, and replicated data is encrypted by default using destination security controls.
Credentials: User metadata is encrypted in transit and at rest, and access to it is tracked and audited.
Processing costs: Datastream charges for processed data; idle streams incur no cost, and other Google Cloud resources used are billed separately.
Event delivery: Events are delivered at least once and their order is not guaranteed.
Event size limits: The documented event size limit is 20 MB for BigQuery destinations and 100 MB for Cloud Storage destinations.
Use cases: Google identifies analytics, database replication, migration, synchronization, and event-driven architectures as Datastream use cases.
Administration: Datastream can be administered through the Google Cloud console, Google Cloud CLI, and REST API.
Price from: $0.40/mo
