class="devsite-article-body clearfix "> <meta name="keywords" value="docType:Concept, content:overview, use cases"> <meta name="description" content="Behavior, use cases and benefits of using Datastream as a change data capture solution."> <h2 id="behavior_and_use_cases" data-text="Behavior and use cases" tabindex="-1">Behavior and use cases</h2> <p>Datastream gives users the ability to bring source data from a Relational Database Management System (RDBMS) and other sources into destinations such as BigQuery and Cloud Storage in near real-time fashion. This provides for downstream use-cases such as loading the data into BigQuery for data warehousing and analytics, or running Spark jobs over the data for artificial intelligence and machine learning use cases.</p> <h2 id="concepts" data-text="Concepts" tabindex="-1">Concepts</h2> <h3 id="change_data_capture" data-text="Change data capture" tabindex="-1">Change data capture</h3> <p>Change data capture (CDC) is a set of <a href="https://en.wikipedia.org/wiki/Software_design_pattern">software design patterns</a> used to determine (and track) the data that has changed so that action can be taken using the changed data. CDC is also an approach to data integration that&#39;s based on the identification, capture, and delivery of the changes made to enterprise data sources.</p> <h3 id="event_sourcing" data-text="Event sourcing" tabindex="-1">Event sourcing</h3> <p>Introduced in 2005, <a href="https://martinfowler.com/eaaDev/EventSourcing.html">event sourcing</a> is a design pattern where every change to a state of an application is captured in an event object. Utilizing event sourcing, an application can rebuild its state, perform <a href="https://en.wikipedia.org/wiki/Point-in-time_recovery">point-in-time recovery</a> (by processing the event until that point), recompute the state in case of a change in logic, or enable <a href="https://martinfowler.com/bliki/CQRS.html">Command Query Responsibility Segregation (CQRS)</a> design. With the evolution of tools for real-time event processing, many applications are moving to the event sourcing model. Historically, transactional databases were always event-oriented, because of <a href="https://en.wikipedia.org/wiki/ACID">atomicity, consistency, isolation, and durability (ACID)</a> requirements.</p> <h3 id="transactional_databases" data-text="Transactional databases" tabindex="-1">Transactional databases</h3> <p>In a transactional database, the set of operations that the database is going to perform is usually written to a <a href="https://en.wikipedia.org/wiki/Write-ahead_logging">write-ahead log (WAL)</a> before any operations are executed on the storage engine. After an operation is executed on the storage engine and is committed to the WAL, the operation is considered to be successful. Using WAL enables atomicity and durability, and also allows high-fidelity replication of the database. Some databases will write to the log the exact operation that will happen on the storage level (for example, <code translate="no" dir="ltr">write 0x41 on location 20</code>), so those actions can only be replicated (or redone) on the same storage engine. Other databases will log a complete logical statement (or row) that can be re-executed on a different storage engine.</p> <h3 id="eventsandstreams" data-text="Events and streams" tabindex="-1">Events and streams</h3> <p>Datastream ingests a lot of data in near real-time fashion from a variety of sources, and makes the data available for consumption in the destination. The unit of data stored by Datastream is an event. A stream represents continuous ingestion of events from a source and writing them to a destination.</p> <h3 id="unified_types" data-text="Unified types" tabindex="-1">Unified types</h3> <p>Data sources have their own types, some specific to the database itself, and some that are generic and are shared across databases. Because there are many different sources that generate streams to a unified destination, there must be a standard, unified way to represent the original source type across all sources. The <a href="/datastream/docs/unified-types#unitypes">unified type</a> is a common and lossless way to represent data types across all sources so that they can be consumed in a cohesive manner. The unified types supported by Datastream will represent the superset of all normalized types across all supported source systems so that all types can be supported losslessly.</p> <h3 id="entitycontext" data-text="Entity context" tabindex="-1">Entity context</h3> <p>Datastream has five entities:</p> <ul> <li><b>Private connectivity configurations</b> enable Datastream to communicate with data sources over a secure, private network connection. This communication happens through Virtual Private Cloud (VPC) peering.</li> <li><b>Connection profiles</b> represent connectivity information to a specific source or destination database.</li> <li><b>Streams</b> represent a source and destination connection profile pair, along with stream-specific settings. </li> <li><b>Objects</b> represent a sub-portion of a stream. For example, a database stream has a data object for every table being streamed.</li> <li><b>Events</b> represent every data manipulation language (DML) change for a given object.</li> </ul> <p>After <a href="/datastream/docs/create-a-private-connectivity-configuration">creating a private connectivity configuration</a>, you can connect to sources hosted in Google Cloud or elsewhere over a private communication channel. Private connectivity is optional, Datastream also supports other modes of connectivity over public networks.</p> <p>After <a href="/datastream/docs/create-connection-profiles">creating a connection profile</a> for a source and a destination, you can create streams that use the information stored in the connection profiles to transfer data from the source to the destination.</p> <p>After <a href="/datastream/docs/create-a-stream">creating a stream</a>, Datastream connects to the source directly, consumes content, and then processes and writes the events to the destination based on the <a href="/datastream/docs/events-and-streams#events">event structure</a>.</p> <p>Private connectivity configurations and connection profiles can be managed separately from streams for easy reuse, and because frequently, in enterprises, the person who can establish connectivity to a source or destination isn&#39;t the same person as the one creating the stream.</p> <h2 id="features" data-text="Features" tabindex="-1">Features</h2> <p>Features for Datastream include:</p> <ul> <li><b>Serverless:</b> You can configure a stream and the data starts moving. There are no installation, resource allocation, or maintenance overheads. As data volumes grow and shrink, Datastream&#39;s autoscaling capabilities allocate resources to keep data moving in near real-time, automatically.</li> <li><b>Unified Avro-based type schema:</b> Datastream enables source-independent processing by converting all source-specific data types into a unified Datastream type schema, based on Avro types.</li> <li><b>Stream historical and CDC data:</b> Datastream streams both historical and CDC source data in near real-time, simultaneously.</li> <li><p><b>Oracle CDC without additional licenses:</b> Datastream provides LogMiner-based CDC streaming from any Oracle source version 11.2g and above, without the need to pay for additional licenses or software installations.</p></li> <li><p><b>BigQuery destination:</b> Changes in the source are replicated continuously to BigQuery tables in near real-time. Data in BigQuery is almost immediately available for analytics.</p></li> <li><p><b>Cloud Storage destination:</b> CDC data is written to self-describing Avro or JSON files in Cloud Storage continually. This information is consumable for additional processing, either directly in place or by loading downstream to another destination such as Spanner.</p></li> </ul> <h2 id="use_cases" data-text="Use cases" tabindex="-1">Use cases</h2> <p>There are three main scenarios for using Datastream:</p> <ul> <li><strong>Data integration</strong>: Data streams from databases and Software-as-a-Service (SaaS) cloud services can feed a near real-time data integration pipeline by loading data into BigQuery.</li> <li><strong>Streaming analytics</strong>: Changes in databases are ingested into streaming pipelines such as with Dataflow for fraud detection, security event processing, and anomaly detection.</li> <li><strong>Near real-time availability of data changes</strong>: Availability of data changes in near real-time powers artificial intelligence and machine learning applications to prevent churn or increase engagement using marketing efforts or by feeding back into production systems.</li> </ul> <h2 id="behavior_overview" data-text="Behavior overview" tabindex="-1">Behavior overview</h2> <p>Datastream enables customers stream ongoing changes from multiple data sources directly into Google Cloud.</p> <h3 id="sources" data-text="Sources" tabindex="-1">Sources</h3> <ul> <li>There is setup work required for a source to be used with Datastream, including authentication and additional configuration options.</li> <li>Each source generates events that reflect all data manipulation language (DML) changes.</li> <li>Each stream can backfill historical data, as well as stream ongoing changes into the destination.</li> </ul> <h3 id="destinations" data-text="Destinations" tabindex="-1">Destinations</h3> <p>Datastream supports BigQuery and Cloud Storage as <a href="/datastream/docs/destination#destination">destinations</a>. When the stream is created, the desired BigQuery datasets or Cloud Storage bucket are defined.</p> <h3 id="eventdelivery" data-text="Event delivery" tabindex="-1">Event delivery</h3> <ul> <li>The <a href="/datastream/docs/events-and-streams#ordering">event order</a> isn&#39;t guaranteed. <a href="/datastream/docs/events-and-streams#events">Event metadata</a> includes information that can be used to order the events.</li> <li>The <a href="/datastream/docs/events-and-streams#consistency">event delivery</a> occurs at least once. Event metadata includes data that can be used to remove any duplicate data in the destination.</li> <li>The event size is limited to 20 MB per event for BigQuery destinations and 100 MB per event for Cloud Storage destinations.</li> </ul> <p>To learn more about events, see <a href="#eventsandstreams">Events and streams</a>.</p> <h3 id="high_availability_and_disaster_recovery" data-text="High availability and disaster recovery" tabindex="-1">High availability and disaster recovery</h3> <p>This section contains information about how Datastream handles scenarios associated with high availability and disaster recovery.</p> <ul> <li><p><b>High availability:</b> Datastream is a regional service, running on multiple <a href="/docs/geography-and-regions#regions_and_zones">zones in each region</a>. A single-zone failure in any one region will not impact the availability or quality of the service in other zones.</p></li> <li><p><b>Disaster recovery:</b> If there&#39;s a failure in a region, then any streams running on that region will be down for the duration of the outage. After the outage is resolved, Datastream will continue exactly where it left off, and any data that hasn&#39;t been written to the destination will be retrieved again from the source. In this case, duplicates of data may reside in the destination. See <a href="#eventdelivery">Event delivery</a> for more information on removing the duplicate data.</p></li> </ul> <h3 id="initial_data_and_cdc_data" data-text="Initial data and CDC data" tabindex="-1">Initial data and CDC data</h3> <p>Because data sources have data that existed before the time that the source was connected to a stream (historical data), Datastream generates events both from the historical data as well as data changes happening in real-time.</p> <p>To ensure fast data access, the historical data and the real-time data changes are replicated simultaneously to the destination. The <a href="/datastream/docs/events-and-streams#events">event metadata</a> indicates whether that event is from the backfill or from the CDC.</p> <h2 id="whatsnext" data-text="What's next" tabindex="-1">What's next</h2> <ul> <li>Find out more about <a href="/datastream/docs/overview">Datastream</a>.</li> <li>Find out more about <a href="/datastream/docs/events-and-streams">events and streams</a>.</li> <li>Learn about <a href="/datastream/docs/unified-types">unified types mappings</a>.</li> <li>Learn more about <a href="/datastream/docs/sources">sources</a> that Datastream supports.</li> <li>Learn more about <a href="/datastream/docs/destinations">destinations</a> that Datastream supports.</li> <li>Find out how to create <a href="/datastream/docs/create-a-private-connectivity-configuration">private connectivity configurations</a>, <a href="/datastream/docs/create-connection-profiles">connection profiles</a> and <a href="/datastream/docs/create-a-stream">streams</a>.</li> </ul> <devsite-hats-survey class="nocontent" hats-id="Nd7nTix2o0eU5NUYprb0ThtUc5jf" listnr-id="83405"></devsite-hats-survey> </div> <devsite-thumb-rating position="footer"> </devsite-thumb-rating> <devsite-feedback position="footer" project-name="Datastream" product-id="5165865" bucket="Documentation" context="" version="t-devsite-webserver-20250218-r02-rc00.467092460105212566" data-label="Send Feedback Button" track-type="feedback" track-name="sendFeedbackLink" track-metadata-position="footer" class="nocontent" project-icon="https://www.gstatic.com/devrel-devsite/prod/vd2dddc2199cd18ccf014281c77515e1e906f6b98324fd2a8b5fa9e92b09e8018/cloud/images/favicons/onecloud/super_cloud.png" > <button> Send feedback </button> </devsite-feedback> <div class="devsite-floating-action-buttons"> </div> </article> <devsite-content-footer class="nocontent"> <p>Except as otherwise noted, the content of this page is licensed under the <a href="https://creativecommons.org/licenses/by/4.0/">Creative Commons Attribution 4.0 License</a>, and code samples are licensed under the <a href="https://www.apache.org/licenses/LICENSE-2.0">Apache 2.0 License</a>.
