Datastream 是一种无服务器且易于使用的变更数据捕获 (CDC) 和复制服务，可让您可靠地同步数据，同时将延迟时间缩至最短。
Datastream 可将数据从运营数据库无缝复制到 BigQuery。此外，Datastream 还支持将变更事件流写入 Cloud Storage，并提供与 Dataflow 模板的简化集成，以构建用于将数据加载到各种目标位置（例如 Cloud SQL 和 Spanner）的自定义工作流。您还可以使用 Datastream 直接利用 Cloud Storage 中的事件流来实现事件驱动型架构。Datastream 支持 Oracle、MySQL、SQL Server 和 PostgreSQL（包括 AlloyDB for PostgreSQL 和 AlloyDB Omni）来源。

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. Datastream supports Oracle, MySQL,\nSQL Server, and PostgreSQL (including AlloyDB for PostgreSQL and AlloyDB Omni) sources.\n\n\n[Learn more](/datastream/docs/overview) about Datastream.\n[Get started for free](https://console.cloud.google.com/freetrial) \n\n#### Start your proof of concept with $300 in free credit\n\n- Get access to Gemini 2.0 Flash Thinking\n- Free monthly usage of popular products, including AI APIs and BigQuery\n- No automatic charges, no commitment \n[View free product offers](/free/docs/free-cloud-features#free-tier) \n\n#### Keep exploring with 20+ always-free products\n\n\nAccess 20+ free products for common use cases, including AI APIs, VMs, data warehouses,\nand more.\n\nDocumentation resources\n-----------------------\n\nFind quickstarts and guides, review key references, and get help with common issues. \nformat_list_numbered\n\n### Guides\n\n-\n\n [Quickstart: Replicate data to BigQuery in near real-time with Datastream](/datastream/docs/quickstart-replication-to-bigquery)\n\n-\n\n [Quickstart: Stream changes to data in near real-time with Datastream](/datastream/docs/quickstart-change-streaming-to-gcs)\n\n-\n\n [Create a private connectivity configuration](/datastream/docs/create-a-private-connectivity-configuration)\n\n-\n\n [Create connection profiles](/datastream/docs/create-connection-profiles)\n\n-\n\n [Create a stream](/datastream/docs/create-a-stream)\n\n-\n\n [Run a stream](/datastream/docs/run-a-stream)\n\n-\n\n [Manage backfill for the objects of a stream](/datastream/docs/manage-backfill-for-the-objects-of-a-stream)\n\nfind_in_page\n\n### Reference\n\n-\n\n [REST reference](/datastream/docs/reference/rest)\n\n-\n\n [Use the Datastream API](/datastream/docs/use-the-datastream-api)\n\n-\n\n [Use the gcloud CLI](/datastream/docs/use-the-cloud-sdk)\n\n-\n\n [gcloud reference](/sdk/gcloud/reference/datastream)\n\ninfo\n\n### Resources\n\n-\n\n [Getting support](/support)\n\n-\n\n [Pricing](/datastream/pricing)\n\n-\n\n [Quotas and limits](/datastream/docs/quotas)\n\n-\n\n [IP allowlists and regions](/datastream/docs/ip-allowlists-and-regions)\n\n-\n\n [Release notes](/datastream/docs/release-notes)\n\n-\n\n [Audit logging information](/datastream/docs/audit-logging)\n\n-\n\n [FAQ](/datastream/docs/faq)\n\nRelated resources\n-----------------\n\nExplore self-paced training, use cases, reference architectures, and code samples with examples of how to use and connect Google Cloud services.
