• Product Documentation
• Client Library Documentation

Quickstart

If you are using Maven with BOM, add this to your pom.xml file

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>20.2.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<dependencies>
  <dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-bigquerystorage</artifactId>
  </dependency>

If you are using Maven without BOM, add this to your dependencies:

<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-bigquerystorage</artifactId>
  <version>1.20.2</version>
</dependency>

If you are using Gradle 5.x or later, add this to your dependencies

implementation platform('com.google.cloud:libraries-bom:20.2.0')

compile 'com.google.cloud:google-cloud-bigquerystorage'

If you are using Gradle without BOM, add this to your dependencies

compile 'com.google.cloud:google-cloud-bigquerystorage:1.20.2'

If you are using SBT, add this to your dependencies

libraryDependencies += "com.google.cloud" % "google-cloud-bigquerystorage" % "1.20.2"

Authentication

See the Authentication section in the base directory's README.

Getting Started

Prerequisites

You will need a Google Cloud Platform Console project with the BigQuery Storage API enabled. You will need to enable billing to use Google BigQuery Storage. Follow these instructions to get your project set up. You will also need to set up the local development environment by installing the Google Cloud SDK and running the following commands in command line: gcloud auth login and gcloud config set project [YOUR PROJECT ID].

Installation and setup

You'll need to obtain the google-cloud-bigquerystorage library. See the Quickstart section to add google-cloud-bigquerystorage as a dependency in your code.

About BigQuery Storage

BigQuery Storage is an API for reading data stored in BigQuery. This API provides direct, high-throughput read access to existing BigQuery tables, supports parallel access with automatic liquid sharding, and allows fine-grained control over what data is returned.

See the BigQuery Storage client library docs to learn how to use this BigQuery Storage Client Library.
