Key features
Key features
Replication of operational data into BigQuery
Datastream uses BigQuery’s Change Data Capture (CDC) functionality and Storage Write API to efficiently replicate updates directly from source systems in near real time. You no longer need replication solutions that waste valuable resources on complex data pipelines, self-managed staging tables, tricky merge logic, or manual data type conversion.
Simplified setup
Datastream allows you to start replicating data into BigQuery in a few steps. Just configure your source database, connection type, and destination in BigQuery, and you’re all set. Datastream for BigQuery will backfill historical data and continuously replicate new changes as they happen.
Streaming data from relational databases
Datastream reads and delivers every change—insert, update, and delete—from your MySQL, PostgreSQL, AlloyDB, SQL Server, and Oracle databases into BigQuery with minimal latency. The source database can be hosted on-premises, on Google Cloud services, such as Cloud SQL or Bare Metal Solution for Oracle, or anywhere else on any cloud. An agentless and Google-native service built specifically for BigQuery, it reliably streams every event as it happens.
Schema drift resolution
As source schemas change, Datastream seamlessly handles schema drift and automatically replicates new columns and tables added in the source to BigQuery.
Security by design
Datastream supports multiple secure, private connectivity methods to protect data in transit. Data is also encrypted at rest.
Customers
Customers use Datastream and BigQuery to enable real-time insights
With Datastream, we have a single tool to perform seamless, near real-time replication of our operational data to BigQuery. Datastream helps us get much quicker insights on our operational data, deliver more stable data products, and better address our business needs.

Use cases
Use cases
Serverless replication to BigQuery
Datastream reads change events (inserts, updates, and deletes) from source databases and writes them in BigQuery tables in near real time. This enables you to enrich existing BigQuery data warehouses and ML models with transactional data, such as retail purchases, to build a more complete end-to-end picture of data. Datastream will backfill historical data, continuously replicate new changes as they happen, and seamlessly handle schema changes.
