AppendRowsRequest

Request message for AppendRows. Due to the nature of AppendRows being a bidirectional streaming RPC, certain parts of the AppendRowsRequest need only be specified for the first request sent each time the gRPC network connection is opened/reopened. The size of a single AppendRowsRequest must be less than 10 MB in size. Requests larger than this return an error, typically INVALID_ARGUMENT.

BaseBigQueryReadClient

Service Description: BigQuery Read API.

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

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:

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.

Exceptions

Exceptions.AppendSerializtionError

This exception is thrown from JsonStreamWriter#append() when the client side Json to Proto serializtion fails. It can also be thrown by the server in case rows contains invalid data. The exception contains a Map of indexes of faulty rows and the corresponding error message.

Exceptions.FieldParseError

This exception is used internally to handle field level parsing errors.

Exceptions.InflightBytesLimitExceededException

Exceptions.InflightLimitExceededException

If FlowController.LimitExceededBehavior is set to Block and inflight limit is exceeded, this exception will be thrown. If it is just a spike, you may retry the request. Otherwise, you can increase the inflight limit or create more StreamWriter to handle your traffic.

Exceptions.InflightRequestsLimitExceededException

Exceptions.JsonDataHasUnknownFieldException

Input Json data has unknown field to the schema of the JsonStreamWriter. User can either turn on IgnoreUnknownFields option on the JsonStreamWriter, or if they don't want the error to be ignored, they should recreate the JsonStreamWriter with the updated table schema.

Exceptions.OffsetAlreadyExists

Offset already exists. This indicates that the append request attempted to write data to an offset before the current end of the stream. This is an expected exception when ExactOnce is enforced. You can safely ignore it, and keep appending until there is new data to append.

Exceptions.OffsetOutOfRange

Offset out of range. This indicates that the append request is attempting to write data to a point beyond the current end of the stream. To append data successfully, you must either specify the offset corresponding to the current end of stream, or omit the offset from the append request. It usually means a bug in your code that introduces a gap in appends.

Exceptions.SchemaMismatchedException

There was a schema mismatch due to bigquery table with fewer fields than the input message. This can be resolved by updating the table's schema with the message schema.

Exceptions.StorageException

Main Storage Exception. Might contain map of streams to errors for that stream.

Exceptions.StreamFinalizedException

The write stream has already been finalized and will not accept further appends or flushes. To send additional requests, you will need to create a new write stream via CreateWriteStream.

Exceptions.StreamNotFound

The stream is not found. Possible causes include incorrectly specifying the stream identifier or attempting to use an old stream identifier that no longer exists. You can invoke CreateWriteStream to create a new stream.

Exceptions.StreamWriterClosedException

This writer instance has either been closed by the user explicitly, or has encountered non-retriable errors.

To continue to write to the same stream, you will need to create a new writer instance.
