Classes

Because AppendRows is a bidirectional streaming RPC, certain parts of the AppendRowsRequest need only be specified for the first request before switching table destinations. You can also switch table destinations within the same connection for the default stream.

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().

Methods
Method	Description	Method Variants
CreateReadSession	Creates a new read session. A read session divides the contents of a BigQuery table into one or more streams, which can then be used to read data from the table. The read session also specifies properties of the data to be read, such as a list of columns or a push-down filter describing the rows to be returned. A particular row can be read by at most one stream. When the caller has reached the end of each stream in the session, then all the data in the table has been read. Data is assigned to each stream such that roughly the same number of rows can be read from each stream. Because the server-side unit for assigning data is collections of rows, the API does not guarantee that each stream will return the same number or rows. Additionally, the limits are enforced based on the number of pre-filtered rows, so some filters can lead to lopsided assignments. Read sessions automatically expire 6 hours after they are created and do not require manual clean-up by the caller.	Request object method variants only take one parameter, a request object, which must be constructed before the call. createReadSession(CreateReadSessionRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. createReadSession(ProjectName parent, ReadSession readSession, int maxStreamCount) createReadSession(String parent, ReadSession readSession, int maxStreamCount) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createReadSessionCallable()
ReadRows	Reads rows from the stream in the format prescribed by the ReadSession. Each response contains one or more table rows, up to a maximum of 100 MiB per response; read requests which attempt to read individual rows larger than 100 MiB will fail. Each request also returns a set of stream statistics reflecting the current state of the stream.	Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. readRowsCallable()
SplitReadStream	Splits a given `ReadStream` into two `ReadStream` objects. These `ReadStream` objects are referred to as the primary and the residual streams of the split. The original `ReadStream` can still be read from in the same manner as before. Both of the returned `ReadStream` objects can also be read from, and the rows returned by both child streams will be the same as the rows read from the original stream. Moreover, the two child streams will be allocated back-to-back in the original `ReadStream`. Concretely, it is guaranteed that for streams original, primary, and residual, that original[0-j] = primary[0-j] and original[j-n] = residual[0-m] once the streams have been read to completion.	Request object method variants only take one parameter, a request object, which must be constructed before the call. splitReadStream(SplitReadStreamRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. splitReadStreamCallable()

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.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.

BigQueryReadClient

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:

 
 try (BigQueryReadClient BigQueryReadClient = BigQueryReadClient.create()) {
   String parent = "";
   ReadSession readSession = ReadSession.newBuilder().build();
   int maxStreamCount = 0;
   ReadSession response = BigQueryReadClient.createReadSession(parent, readSession, maxStreamCount);
 }

Note: close() needs to be called on the BigQueryReadClient 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:

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.
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.
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.

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

To customize credentials:

 
 BigQueryReadSettings BigQueryReadSettings =
     BigQueryReadSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 BigQueryReadClient BigQueryReadClient =
     BigQueryReadClient.create(BigQueryReadSettings);

To customize the endpoint:

 
 BigQueryReadSettings BigQueryReadSettings =
     BigQueryReadSettings.newBuilder().setEndpoint(myEndpoint).build();
 BigQueryReadClient BigQueryReadClient =
     BigQueryReadClient.create(BigQueryReadSettings);

Methods
Method	Description	Method Variants
CreateWriteStream	Creates a write stream to the given table. Additionally, every table has a special stream named '_default' to which data can be written. This stream doesn't need to be created using CreateWriteStream. It is a stream that can be used simultaneously by any number of clients. Data written to this stream is considered committed as soon as an acknowledgement is received.	Request object method variants only take one parameter, a request object, which must be constructed before the call. createWriteStream(CreateWriteStreamRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. createWriteStream(TableName parent, WriteStream writeStream) createWriteStream(String parent, WriteStream writeStream) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createWriteStreamCallable()
AppendRows	Appends data to the given stream. If `offset` is specified, the `offset` is checked against the end of stream. The server returns `OUT_OF_RANGE` in `AppendRowsResponse` if an attempt is made to append to an offset beyond the current end of the stream or `ALREADY_EXISTS` if user provides an `offset` that has already been written to. User can retry with adjusted offset within the same RPC connection. If `offset` is not specified, append happens at the end of the stream. The response contains an optional offset at which the append happened. No offset information will be returned for appends to a default stream. Responses are received in the same order in which requests are sent. There will be one response for each successful inserted request. Responses may optionally embed error information if the originating AppendRequest was not successfully processed. The specifics of when successfully appended data is made visible to the table are governed by the type of stream: For COMMITTED streams (which includes the default stream), data is visible immediately upon successful append. For BUFFERED streams, data is made visible via a subsequent `FlushRows` rpc which advances a cursor to a newer offset in the stream. For PENDING streams, data is not made visible until the stream itself is finalized (via the `FinalizeWriteStream` rpc), and the stream is explicitly committed via the `BatchCommitWriteStreams` rpc.	Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. appendRowsCallable()
GetWriteStream	Gets information about a write stream.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getWriteStream(GetWriteStreamRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getWriteStream(WriteStreamName name) getWriteStream(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getWriteStreamCallable()
FinalizeWriteStream	Finalize a write stream so that no new data can be appended to the stream. Finalize is not supported on the '_default' stream.	Request object method variants only take one parameter, a request object, which must be constructed before the call. finalizeWriteStream(FinalizeWriteStreamRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. finalizeWriteStream(WriteStreamName name) finalizeWriteStream(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. finalizeWriteStreamCallable()
BatchCommitWriteStreams	Atomically commits a group of `PENDING` streams that belong to the same `parent` table. Streams must be finalized before commit and cannot be committed multiple times. Once a stream is committed, data in the stream becomes available for read operations.	Request object method variants only take one parameter, a request object, which must be constructed before the call. batchCommitWriteStreams(BatchCommitWriteStreamsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. batchCommitWriteStreams(TableName parent) batchCommitWriteStreams(String parent) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. batchCommitWriteStreamsCallable()
FlushRows	Flushes rows to a BUFFERED stream. If users are appending rows to BUFFERED stream, flush operation is required in order for the rows to become available for reading. A Flush operation flushes up to any previously flushed offset in a BUFFERED stream, to the offset specified in the request. Flush is not supported on the _default stream, since it is not BUFFERED.	Request object method variants only take one parameter, a request object, which must be constructed before the call. flushRows(FlushRowsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. flushRows(WriteStreamName writeStream) flushRows(String writeStream) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. flushRowsCallable()

It maintains all StreamWriter functions, but also provides an additional feature: schema update support, where if the BigQuery table schema is updated, users will be able to ingest data on the new schema after some time (in order of minutes).

SchemaAwareStreamWriter<T>

A StreamWriter that can write data to BigQuery tables. The SchemaAwareStreamWriter is built on top of a StreamWriter, and it converts all data to Protobuf messages using provided converter then calls StreamWriter's append() method to write to BigQuery tables. It maintains all StreamWriter functions, but also provides an additional feature: schema update support, where if the BigQuery table schema is updated, users will be able to ingest data on the new schema after some time (in order of minutes).

NOTE: The schema update ability will be disabled when you pass in a table schema explicitly through the writer. It is recommended that user either use JsonStreamWriter (which fully manages table schema) or StreamWriter (which accepts proto format in raw and user will handle the schema update event themsevles). If you use this class, you need to be very cautious about possible mistmach between the writer's schema and the input data, any mismatch of the two will cause data corruption.

Exceptions

Exceptions.AppendSerializationError

This exception is thrown from <xref uid="com.google.cloud.bigquery.storage.v1.SchemaAwareStreamWriter.append(java.lang.Iterable<T>)" data-throw-if-not-resolved="false">SchemaAwareStreamWriter#append(Iterable) when the client side Proto serialization 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.AppendSerializtionError

This class has a typo in the name. It will be removed soon. Please use AppendSerializationError

Exceptions.DataHasUnknownFieldException

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

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

This class is replaced by a generic one. It will be removed soon. Please use DataHasUnknownFieldException

Exceptions.MaximumRequestCallbackWaitTimeExceededException

The connection was shut down because a callback was not received within the maximum wait time.

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.
