Google Cloud BigQuery Storage Java Client

Java idiomatic client for Cloud BigQuery Storage.

Kokoro CI Maven

Note: This client is a work-in-progress, and may occasionally make backwards-incompatible changes.

Quickstart

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

   <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>libraries-bom</artifactId>
        <version>3.5.0</version>
        <type>pom</type>
        <scope>import</scope>
       </dependency>
     </dependencies>
    </dependencyManagement>
    
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-bigquerystorage</artifactId>
    </dependency>

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

    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-bigquerystorage</artifactId>
      <version>0.121.0-beta</version>
    </dependency>

If you are using Gradle, add this to your dependencies

compile 'com.google.cloud:google-cloud-bigquerystorage:0.121.0-beta'

If you are using SBT, add this to your dependencies

libraryDependencies += "com.google.cloud" % "google-cloud-bigquerystorage" % "0.121.0-beta"

Authentication

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

About Cloud BigQuery Storage

Cloud 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 Cloud BigQuery Storage client library docs to learn how to read date stored in BigQuery using this library.

Getting Started

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.

Transport

Cloud BigQuery Storage uses gRPC for the transport layer.

Java Versions

Java 7 or above is required for using this client.

Testing

This library has tools to help make tests for code using Cloud BigQuery Storage.

Versioning

This library follows Semantic Versioning.

It is currently in major version zero (0.y.z), which means that anything may change at any time and the public API should not be considered stable.

Contributing

Contributions to this library are always welcome and highly encouraged.

See google-cloud's CONTRIBUTING documentation and the shared documentation for more information on how to get started.
