This page describes how to use the Dataflow connector forSpanner to import, export, and modify data in SpannerGoogleSQL-dialect databases and PostgreSQL-dialect databases.Dataflow is a managed service for transforming and enrichingdata. The Dataflow connector for Spanner lets you readdata from and write data to Spanner in a Dataflowpipeline, optionally transforming or modifying the data. You can also createpipelines that transfer data between Spanner and otherGoogle Cloud products.The Dataflow connector is the recommended method for efficientlymoving data into and out of Spanner in bulk. It's also therecommended method for performing large transformations to a database which arenot supported by Partitioned DML, such as table moves and bulk deletesthat require a JOIN. When working with individual databases, there are othermethods you can use to import and export data:Use the Google Cloud console to export an individual database fromSpanner to Cloud Storage in Avroformat.Use the Google Cloud console to import a database back intoSpanner from files you exported to Cloud Storage.Use the REST API or Google Cloud CLI to run export or importjobs from Spanner to Cloud Storage and back also usingAvro format.The Dataflow connector for Spanner is part of theApache Beam Java SDK, and it provides an API for performing the previousactions. For more information about some of the concepts discussed in this page,such as PCollection objects and transforms, see the Apache Beam programmingguide.Add the connector to your Maven projectTo add the Google Cloud Dataflow connector to a Mavenproject, add the beam-sdks-java-io-google-cloud-platform Maven artifact toyour pom.xml file as a dependency.For example, assuming that your pom.xml file sets beam.version to theappropriate version number, you would add the following dependency: org.apache.beam beam-sdks-java-io-google-cloud-platform ${beam.version}Read data from SpannerTo read from Spanner, apply the SpannerIO.readtransform. Configure the read using the methods in theSpannerIO.Read class. Applying the transform returns aPCollection, where each element in the collectionrepresents an individual row.

In the next section.Setting up cross-cloud connectivity to SpannerEstablishing cross-cloud connectivity from a third-party cloud provider to Spanner is a straightforward process. The following section provides a step-by-step guide on setting up this connection.1. Physical connectivityThe first thing you will need to set up is a Virtual Private Cloud (VPC) network that you can connect to from other clouds. You can think of a VPC network as similar to a physical network, except that it is virtualized within Google Cloud. It consists of a list of regional virtual subnetworks (subnets) in data centers, all connected by a global wide area network. A VPC also enables you to privately connect networks outside of Google to Google Cloud products.(a) Set up VPC network using Google Cloud consoleSimilarly, you will need to have a VPC network on the other Cloud Provider into which to terminate connectivity.Next, you can connect your Google Cloud VPC network to your third-party public cloud environment through Cross-Cloud Interconnect. Go to the Interconnect console and choose Cross-Cloud Interconnect to order a new Cross-Cloud connection:(b) Set up Cross-Cloud Interconnect using Google Cloud consoleNext, you can choose the public cloud provider you’d like to connect to, along with the location and capacity.If you are using regional Spanner, then you should build the connection in the same location as the Spanner region to get the best latency. For multi-regional Spanner, we recommend setting up Interconnects in all the read-write and read-only regions. For example, if you use nam3 configuration, you can set

Spanner is a fully managed database service for both relational and non-relational workloads that offers strong consistency at global scale, high performance at virtually unlimited scale, and high availability with up to five 9s SLA. And as cross-cloud and hybrid cloud strategies gain traction, customers are increasingly seeking the flexibility to utilize Spanner's exceptional database capabilities while running their compute stack on a third-party cloud provider.Key considerations for such cross-cloud setups include:Latency: Customers want their application response times to be low for OLTP workloads.Security: With data traversing cloud boundaries and the sensitivity of information stored in Spanner, secure data transfer is paramount.Availability: Spanner boasts a high SLA, which our customers appreciate. The cross-cloud setup must similarly maintain a high SLA.Ease of setup: Establishing cross-cloud access that addresses the first three areas can be complex.Cost effectiveness: With data traffic flowing between clouds, the cross-cloud solution must be cost-effective.This blog explores how to use Google Cloud’s Cross-Cloud Interconnect to achieve the aforementioned goals.Cross-Cloud InterconnectIn the simplest model, applications can connect to Spanner at spanner.googleapis.com over the public internet. However, customers with increased reliability, latency, security and privacy requirements prefer to connect their workloads to their database environments privately.For application owners who leverage best-of-breed services from different public cloud providers, they need seamless, robust network connectivity across multiple environments. Google Cloud recently introduced Cross-Cloud Interconnect to its network connectivity portfolio to simplify the consumption of differentiated Google Cloud Services like Spanner, from different public cloud environments.Cross-Cloud Interconnect provides:Simplicity, as it does not require.

When youcreate an instance, you choose an instance configuration, which determineswhere your data is stored, and also the number of nodes to use, which determinesthe amount of serving and storage resources in your instance.Execute the following command to create a Spanner instance in the regionus-central1 with 1 node:gcloud spanner instances create test-instance --config=regional-us-central1 ` --description="Test Instance" --nodes=1Note that this creates an instance with the following characteristics:Instance ID test-instanceDisplay name Test InstanceInstance configuration regional-us-central1 (Regional configurations storedata in one region, while multi-region configurations distribute data acrossmultiple regions.
