Package com.google.cloud.bigquery.storage.v1beta2 (2.45.0)

A client to BigQuery Storage API

The interfaces provided are listed below, along with usage samples.

BaseBigQueryReadClient

Service Description: BigQuery Read API.

The Read API can be used to read data from BigQuery.

New code should use the v1 Read API going forward, if they don't use Write API at the same time.

Sample for BaseBigQueryReadClient:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (BaseBigQueryReadClient baseBigQueryReadClient = BaseBigQueryReadClient.create()) {
   ProjectName parent = ProjectName.of("[PROJECT]");
   ReadSession readSession = ReadSession.newBuilder().build();
   int maxStreamCount = 940837515;
   ReadSession response =
       baseBigQueryReadClient.createReadSession(parent, readSession, maxStreamCount);
 }
 

BigQueryWriteClient

Service Description: BigQuery Write API.

The Write API can be used to write data to BigQuery.

The google.cloud.bigquery.storage.v1 API should be used instead of the v1beta2 API for BigQueryWrite operations.

Sample for BigQueryWriteClient:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (BigQueryWriteClient bigQueryWriteClient = BigQueryWriteClient.create()) {
   TableName parent = TableName.of("[PROJECT]", "[DATASET]", "[TABLE]");
   WriteStream writeStream = WriteStream.newBuilder().build();
   WriteStream response = bigQueryWriteClient.createWriteStream(parent, writeStream);
 }

BaseBigQueryReadClient

Service Description: BigQuery Read API.

The Read API can be used to read data from BigQuery.

New code should use the v1 Read API going forward, if they don't use Write API at the same time.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (BaseBigQueryReadClient baseBigQueryReadClient = BaseBigQueryReadClient.create()) {
   ProjectName parent = ProjectName.of("[PROJECT]");
   ReadSession readSession = ReadSession.newBuilder().build();
   int maxStreamCount = 940837515;
   ReadSession response =
       baseBigQueryReadClient.createReadSession(parent, readSession, maxStreamCount);
 }
 

Note: close() needs to be called on the BaseBigQueryReadClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

  1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
  2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
  3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of BaseBigQueryReadSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 BaseBigQueryReadSettings baseBigQueryReadSettings =
     BaseBigQueryReadSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 BaseBigQueryReadClient baseBigQueryReadClient =
     BaseBigQueryReadClient.create(baseBigQueryReadSettings);
 

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 BaseBigQueryReadSettings baseBigQueryReadSettings =
     BaseBigQueryReadSettings.newBuilder().setEndpoint(myEndpoint).build();
 BaseBigQueryReadClient baseBigQueryReadClient =
     BaseBigQueryReadClient.create(baseBigQueryReadSettings);
 

Please refer to the GitHub repository's samples for more quickstart code snippets.

BaseBigQueryReadSettings

Settings class to configure an instance of BaseBigQueryReadClient.

The default instance has everything set to sensible defaults:

  • The default service address (bigquerystorage.googleapis.com) and default port (443) are used.
  • Credentials are acquired automatically through Application Default Credentials.
  • Retries are configured for idempotent methods but not for non-idempotent methods.

The builder of this class is recursive, so contained classes are themselves builders. When build() is called, the tree of builders is called to create the complete settings object.

For example, to set the total timeout of createReadSession to 30 seconds:


 // This snippet has been automatically generated and should be regarded as a code template only.

CivilTimeEncoder

Ported from ZetaSQL CivilTimeEncoder Original code can be found at: https://github.com/google/zetasql/blob/master/java/com/google/zetasql/CivilTimeEncoder.java Encoder for TIME and DATETIME values, according to civil_time encoding.

The valid range and number of bits required by each date/time field is as the following:

Range and bits for date/time fields
Field Range #Bits
Year [1, 9999] 14
Month [1, 12] 4
Day [1, 31] 5
Hour [0, 23] 5
Minute [0, 59] 6
Second [0, 59]* 6
Micros [0, 999999] 20
Nanos [0, 999999999] 30

* Leap second is not supported.

When encoding the TIME or DATETIME into a bit field, larger date/time field is on the more significant side.

StreamConnection

StreamConnection is responsible for writing requests to a GRPC bidirecional connection.

BigQueryReadGrpc.AsyncService

BigQuery Read API. The Read API can be used to read data from BigQuery. New code should use the v1 Read API going forward, if they don't use Write API at the same time.

BigQueryReadSettings.RetryAttemptListener

BigQueryWriteGrpc.AsyncService

BigQuery Write API. The Write API can be used to write data to BigQuery. The google.cloud.bigquery.storage.v1 API should be used instead of the v1beta2 API for BigQueryWrite operations.
