  - to
```
public BigQueryIO.Write<T> to(SerializableFunction<ValueInSingleWindow<T>,TableDestination> tableFunction)
```
    Writes to table specified by the specified table function. The table is a function of ValueInSingleWindow, so can be determined by the value or by the window.
    If the function produces destinations configured with clustering fields, ensure that withClustering() is also set so that the clustering configurations get properly encoded and decoded.
  - to
```
public BigQueryIO.Write<T> to(DynamicDestinations<T,?> dynamicDestinations)
```
    Writes to the table and schema specified by the DynamicDestinations object.
    If any of the returned destinations are configured with clustering fields, ensure that the passed DynamicDestinations object returns TableDestinationCoderV3 when DynamicDestinations.getDestinationCoder() is called.
  - withFormatFunction
```
public BigQueryIO.Write<T> withFormatFunction(SerializableFunction<T,TableRow> formatFunction)
```
    Formats the user's type into a TableRow to be written to BigQuery.
  - withFormatRecordOnFailureFunction
```
public BigQueryIO.Write<T> withFormatRecordOnFailureFunction(SerializableFunction<T,TableRow> formatFunction)
```
    If an insert failure occurs, this function is applied to the originally supplied T element.
    For BigQueryIO.Write.Method.STREAMING_INSERTS method, the resulting TableRow will be accessed via WriteResult.getFailedInsertsWithErr().
    For BigQueryIO.Write.Method.STORAGE_WRITE_API and BigQueryIO.Write.Method.STORAGE_API_AT_LEAST_ONCE methods, the resulting TableRow will be accessed via WriteResult.getFailedStorageApiInserts().
  - withAvroFormatFunction
```
public BigQueryIO.Write<T> withAvroFormatFunction(SerializableFunction<AvroWriteRequest<T>,GenericRecord> avroFormatFunction)
```
    Formats the user's type into a GenericRecord to be written to BigQuery. The GenericRecords are written as avro using the standard GenericDatumWriter.
    This is mutually exclusive with withFormatFunction(org.apache.beam.sdk.transforms.SerializableFunction<T, com.google.api.services.bigquery.model.TableRow>), only one may be set.
  - withAvroWriter
```
public BigQueryIO.Write<T> withAvroWriter(SerializableFunction<Schema,DatumWriter<T>> writerFactory)
```
    Writes the user's type as avro using the supplied DatumWriter.
    This is mutually exclusive with withFormatFunction(org.apache.beam.sdk.transforms.SerializableFunction<T, com.google.api.services.bigquery.model.TableRow>), only one may be set.
    Overwrites withAvroFormatFunction(org.apache.beam.sdk.transforms.SerializableFunction<org.apache.beam.sdk.io.gcp.bigquery.AvroWriteRequest<T>, org.apache.avro.generic.GenericRecord>) if it has been set.

                                                  SerializableFunction<Schema,DatumWriter<AvroT>> writerFactory)
```
    Convert's the user's type to an avro record using the supplied avroFormatFunction. Records are then written using the supplied writer instances returned from writerFactory.
    This is mutually exclusive with withFormatFunction(org.apache.beam.sdk.transforms.SerializableFunction<T, com.google.api.services.bigquery.model.TableRow>), only one may be set.
    Overwrites withAvroFormatFunction(org.apache.beam.sdk.transforms.SerializableFunction<org.apache.beam.sdk.io.gcp.bigquery.AvroWriteRequest<T>, org.apache.avro.generic.GenericRecord>) if it has been set.
  - withAvroSchemaFactory
```
public BigQueryIO.Write<T> withAvroSchemaFactory(SerializableFunction<TableSchema,Schema> avroSchemaFactory)
```
    Uses the specified function to convert a TableSchema to a Schema.
    If not specified, the TableSchema will automatically be converted to an avro schema.
  - withSchema
```
public BigQueryIO.Write<T> withSchema(TableSchema schema)
```
    Uses the specified schema for rows to be written.
    The schema is required only if writing to a table that does not already exist, and BigQueryIO.Write.CreateDisposition is set to BigQueryIO.Write.CreateDisposition.CREATE_IF_NEEDED.
  - withSchema
```
public BigQueryIO.Write<T> withSchema(ValueProvider<TableSchema> schema)
```
    Same as withSchema(TableSchema) but using a deferred ValueProvider.
  - withJsonSchema
```
public BigQueryIO.Write<T> withJsonSchema(java.lang.String jsonSchema)
```
    Similar to withSchema(TableSchema) but takes in a JSON-serialized TableSchema.
  - withJsonSchema
```
public BigQueryIO.Write<T> withJsonSchema(ValueProvider<java.lang.String> jsonSchema)
```
    Same as withJsonSchema(String) but using a deferred ValueProvider.
  - withSchemaFromView
```
public BigQueryIO.Write<T> withSchemaFromView(PCollectionView<java.util.Map<java.lang.String,java.lang.String>> view)
```
    Allows the schemas for each table to be computed within the pipeline itself.
    The input is a map-valued PCollectionView mapping string tablespecs to JSON-formatted TableSchemas. Tablespecs must be in the same format as taken by to(String).
  - withTimePartitioning
```
public BigQueryIO.Write<T> withTimePartitioning(TimePartitioning partitioning)
```
    Allows newly created tables to include a TimePartitioning class. Can only be used when writing to a single table. If to(SerializableFunction) or to(DynamicDestinations) is used to write dynamic tables, time partitioning can be directly set in the returned TableDestination.
  - withTimePartitioning
```
public BigQueryIO.Write<T> withTimePartitioning(ValueProvider<TimePartitioning> partitioning)
```
    Like withTimePartitioning(TimePartitioning) but using a deferred ValueProvider.
  - withJsonTimePartitioning
```
public BigQueryIO.Write<T> withJsonTimePartitioning(ValueProvider<java.lang.String> partitioning)
```
    The same as withTimePartitioning(com.google.api.services.bigquery.model.TimePartitioning), but takes a JSON-serialized object.
  - withClustering
```
public BigQueryIO.Write<T> withClustering(Clustering clustering)
```
    Specifies the clustering fields to use when writing to a single output table. If to(SerializableFunction) or to(DynamicDestinations) is used to write to dynamic tables, the fields here will be ignored; call withClustering() instead.
  - withJsonClustering
```
public BigQueryIO.Write<T> withJsonClustering(ValueProvider<java.lang.String> jsonClustering)
```
    The same as withClustering(Clustering), but takes a JSON-serialized Clustering object in a deferred ValueProvider. For example: `"{"fields": ["column1", "column2", "column3"]}"`
  - withClustering
```
public BigQueryIO.Write<T> withClustering()
```
    Allows writing to clustered tables when to(SerializableFunction) or to(DynamicDestinations) is used. The returned TableDestination objects should specify the clustering fields per table. If writing to a single table, use withClustering(Clustering) instead to pass a Clustering instance that specifies the static clustering fields to use.
    Setting this option enables use of TableDestinationCoderV3 which encodes clustering information. The updated coder is compatible with non-clustered tables, so can be freely set for newly deployed pipelines, but note that pipelines using an older coder must be drained before setting this option, since TableDestinationCoderV3 will not be able to read state written with a previous version.
  - withCreateDisposition
```
public BigQueryIO.Write<T> withCreateDisposition(BigQueryIO.Write.CreateDisposition createDisposition)
```
    Specifies whether the table should be created if it does not exist.
  - withWriteDisposition
```
public BigQueryIO.Write<T> withWriteDisposition(BigQueryIO.Write.WriteDisposition writeDisposition)
```
    Specifies what to do with existing data in the table, in case the table already exists.
  - withSchemaUpdateOptions
```
public BigQueryIO.Write<T> withSchemaUpdateOptions(java.util.Set<BigQueryIO.Write.SchemaUpdateOption> schemaUpdateOptions)
```
    Allows the schema of the destination table to be updated as a side effect of the write.
    This configuration applies only when writing to BigQuery with BigQueryIO.Write.Method.FILE_LOADS as method.
  - withTableDescription
```
public BigQueryIO.Write<T> withTableDescription(java.lang.String tableDescription)
```
    Specifies the table description.
  - withFailedInsertRetryPolicy
```
public BigQueryIO.Write<T> withFailedInsertRetryPolicy(InsertRetryPolicy retryPolicy)
```
    Specifies a policy for handling failed inserts.
    Currently this only is allowed when writing an unbounded collection to BigQuery. Bounded collections are written using batch load jobs, so we don't get per-element failures. Unbounded collections are written using streaming inserts, so we have access to per-element insert results.
  - withoutValidation
```
public BigQueryIO.Write<T> withoutValidation()
```
    Disables BigQuery table validation.
  - withMethod
```
public BigQueryIO.Write<T> withMethod(BigQueryIO.Write.Method method)
```
    Choose the method used to write data to BigQuery. See the Javadoc on BigQueryIO.Write.Method for information and restrictions of the different methods.
  - withRowMutationInformationFn
```
public BigQueryIO.Write<T> withRowMutationInformationFn(SerializableFunction<T,RowMutationInformation> updateFn)
```
    Allows upserting and deleting rows for tables with a primary key defined. Provides a mapping function that determines how a row is applied to BigQuery (upsert, or delete) along with a sequence number for ordering operations.
    This is supported when using the BigQueryIO.Write.Method.STORAGE_API_AT_LEAST_ONCE insert method, and with either BigQueryIO.Write.CreateDisposition.CREATE_NEVER or BigQueryIO.Write.CreateDisposition.CREATE_IF_NEEDED. For CREATE_IF_NEEDED, a primary key must be specified using withPrimaryKey(java.util.List<java.lang.String>).
  - withDirectWriteProtos
```
public BigQueryIO.Write<T> withDirectWriteProtos(boolean directWriteProtos)
```
  - withLoadJobProjectId
```
public BigQueryIO.Write<T> withLoadJobProjectId(java.lang.String loadJobProjectId)
```
    Set the project the BigQuery load job will be initiated from. This is only applicable when the write method is set to BigQueryIO.Write.Method.FILE_LOADS. If omitted, the project of the destination table is used.
  - withLoadJobProjectId
```
public BigQueryIO.Write<T> withLoadJobProjectId(ValueProvider<java.lang.String> loadJobProjectId)
```
  - withTriggeringFrequency
```
public BigQueryIO.Write<T> withTriggeringFrequency(Duration triggeringFrequency)
```
    Choose the frequency at which file writes are triggered.
    This is only applicable when the write method is set to BigQueryIO.Write.Method.FILE_LOADS or BigQueryIO.Write.Method.STORAGE_WRITE_API, and only when writing an unbounded PCollection.
    Every triggeringFrequency duration, a BigQuery load job will be generated for all the data written since the last load job. BigQuery has limits on how many load jobs can be triggered per day, so be careful not to set this duration too low, or you may exceed daily quota. Often this is set to 5 or 10 minutes to ensure that the project stays well under the BigQuery quota. See Quota Policy for more information about BigQuery quotas.
  - withNumFileShards
```
public BigQueryIO.Write<T> withNumFileShards(int numFileShards)
```
    Control how many file shards are written when using BigQuery load jobs. Applicable only when also setting withTriggeringFrequency(org.joda.time.Duration). To let runner determine the sharding at runtime, set withAutoSharding() instead.
  - withNumStorageWriteApiStreams
```
public BigQueryIO.Write<T> withNumStorageWriteApiStreams(int numStorageWriteApiStreams)
```
    Control how many parallel streams are used when using Storage API writes. Applicable only for streaming pipelines, and when withTriggeringFrequency(org.joda.time.Duration) is also set. To let runner determine the sharding at runtime, set this to zero, or withAutoSharding() instead.
  - withPropagateSuccessfulStorageApiWrites
```
public BigQueryIO.Write<T> withPropagateSuccessfulStorageApiWrites(boolean propagateSuccessfulStorageApiWrites)
```
    If set to true, then all successful writes will be propagated to WriteResult and accessible via the WriteResult.getSuccessfulStorageApiInserts() method.
  - withPropagateSuccessfulStorageApiWrites
```
public BigQueryIO.Write<T> withPropagateSuccessfulStorageApiWrites(java.util.function.Predicate<java.lang.String> columnsToPropagate)
```
    If called, then all successful writes will be propagated to WriteResult and accessible via the WriteResult.getSuccessfulStorageApiInserts() method. The predicate allows filtering out columns from appearing in the resulting PCollection. The argument to the predicate is the name of the field to potentially be included in the output. Nested fields will be presented using . notation - e.g. a.b.c. If you want a nested field included, you must ensure that the predicate returns true for every parent field. e.g. if you want field "a.b.c" included, the predicate must return true for "a" for "a.b" and for "a.b.c".
    The predicate will be invoked repeatedly for every field in every message, so it is recommended that it be as lightweight as possible. e.g. looking up fields in a hash table instead of searching a list of field names.
  - withCustomGcsTempLocation
```
public BigQueryIO.Write<T> withCustomGcsTempLocation(ValueProvider<java.lang.String> customGcsTempLocation)
```
    Provides a custom location on GCS for storing temporary files to be loaded via BigQuery batch load jobs. See "Usage with templates" in BigQueryIO documentation for discussion.
  - withExtendedErrorInfo
```
public BigQueryIO.Write<T> withExtendedErrorInfo()
```
    Enables extended error information by enabling WriteResult.getFailedInsertsWithErr()
    ATM this only works if using BigQueryIO.Write.Method.STREAMING_INSERTS. See withMethod(Method).
  - skipInvalidRows
```
public BigQueryIO.Write<T> skipInvalidRows()
```
    Insert all valid rows of a request, even if invalid rows exist. This is only applicable when the write method is set to BigQueryIO.Write.Method.STREAMING_INSERTS. The default value is false, which causes the entire request to fail if any invalid rows exist.
  - ignoreUnknownValues
```
public BigQueryIO.Write<T> ignoreUnknownValues()
```
    Accept rows that contain values that do not match the schema. The unknown values are ignored. Default is false, which treats unknown values as errors.
  - useAvroLogicalTypes
```
public BigQueryIO.Write<T> useAvroLogicalTypes()
```
    Enables interpreting logical types into their corresponding types (ie. TIMESTAMP), instead of only using their raw types (ie. LONG).
  - ignoreInsertIds
```
public BigQueryIO.Write<T> ignoreInsertIds()
```
    Setting this option to true disables insertId based data deduplication offered by BigQuery. For more information, please see https://cloud.google.com/bigquery/streaming-data-into-bigquery#disabling_best_effort_de-duplication.
  - withKmsKey
```
public BigQueryIO.Write<T> withKmsKey(java.lang.String kmsKey)

```
  - withDefaultMissingValueInterpretation
```
public BigQueryIO.Write<T> withDefaultMissingValueInterpretation(com.google.cloud.bigquery.storage.v1.AppendRowsRequest.MissingValueInterpretation missingValueInterpretation)
```
    Specify how missing values should be interpreted when there is a default value in the schema. Options are to take the default value or to write an explicit null (not an option of the field is also required.). Note: this is only used when using one of the storage write API insert methods.
  - optimizedWrites
```
public BigQueryIO.Write<T> optimizedWrites()
```
    If true, enables new codepaths that are expected to use less resources while writing to BigQuery. Not enabled by default in order to maintain backwards compatibility.
  - useBeamSchema
```
public BigQueryIO.Write<T> useBeamSchema()
```
    If true, then the BigQuery schema will be inferred from the input schema. If no formatFunction is set, then BigQueryIO will automatically turn the input records into TableRows that match the schema.
  - withAutoSharding
```
public BigQueryIO.Write<T> withAutoSharding()
```
    If true, enables using a dynamically determined number of shards to write to BigQuery. This can be used for BigQueryIO.Write.Method.FILE_LOADS, BigQueryIO.Write.Method.STREAMING_INSERTS and BigQueryIO.Write.Method.STORAGE_WRITE_API. Only applicable to unbounded data. If using BigQueryIO.Write.Method.FILE_LOADS, numFileShards set via withNumFileShards(int) will be ignored.
  - withMaxRetryJobs
```
public BigQueryIO.Write<T> withMaxRetryJobs(int maxRetryJobs)
```
    If set, this will set the max number of retry of batch load jobs.
  - withSuccessfulInsertsPropagation
```
public BigQueryIO.Write<T> withSuccessfulInsertsPropagation(boolean propagateSuccessful)
```
    If true, it enables the propagation of the successfully inserted TableRows on BigQuery as part of the WriteResult object when using BigQueryIO.Write.Method.STREAMING_INSERTS. By default this property is set on true. In the cases where a pipeline won't make use of the insert results this property can be set on false, which will make the pipeline let go of those inserted TableRows and reclaim worker resources.
  - withAutoSchemaUpdate
```
public BigQueryIO.Write<T> withAutoSchemaUpdate(boolean autoSchemaUpdate)
```
    If true, enables automatically detecting BigQuery table schema updates. Table schema updates are usually noticed within several minutes. Only supported when using one of the STORAGE_API insert methods.
  - withDeterministicRecordIdFn
```
public BigQueryIO.Write<T> withDeterministicRecordIdFn(SerializableFunction<T,java.lang.String> toUniqueIdFunction)
```
  - withTestServices
```
public BigQueryIO.Write<T> withTestServices(BigQueryServices testServices)
```
  - withMaxFilesPerBundle
```
public BigQueryIO.Write<T> withMaxFilesPerBundle(int maxFilesPerBundle)
```
    Control how many files will be written concurrently by a single worker when using BigQuery load jobs before spilling to a shuffle. When data comes into this transform, it is written to one file per destination per worker. When there are more files than maxFilesPerBundle (DEFAULT: 20), the data is shuffled (i.e. Grouped By Destination), and written to files one-by-one-per-worker. This flag sets the maximum number of files that a single worker can write concurrently before shuffling the data. This flag should be used with caution. Setting a high number can increase the memory pressure on workers, and setting a low number can make a pipeline slower (due to the need to shuffle data).
  - withMaxFileSize
```
public BigQueryIO.Write<T> withMaxFileSize(long maxFileSize)
```
    Controls the maximum byte size per file to be loaded into BigQuery. If the amount of data written to one file reaches this threshold, we will close that file and continue writing in a new file.
    The default value (4 TiB) respects BigQuery's maximum number of source URIs per job configuration.

    BigQuery Load Job Limits
  - withMaxFilesPerPartition
```
public BigQueryIO.Write<T> withMaxFilesPerPartition(int maxFilesPerPartition)
```
    Controls how many files will be assigned to a single BigQuery load job. If the number of files increases past this threshold, we will spill it over into multiple load jobs as necessary.
    The default value (10,000 files) respects BigQuery's maximum number of source URIs per job configuration.

    BigQuery Load Job Limits
  - withMaxBytesPerPartition
```
public BigQueryIO.Write<T> withMaxBytesPerPartition(long maxBytesPerPartition)
```
    Control how much data will be assigned to a single BigQuery load job. If the amount of data flowing into one BatchLoads partition exceeds this value, that partition will be handled via multiple load jobs.
    The default value (11 TiB) respects BigQuery's maximum size per load job limit and is appropriate for most use cases. Reducing the value of this parameter can improve stability when loading to tables with complex schemas containing thousands of fields.

  - withWriteTempDataset
```
public BigQueryIO.Write<T> withWriteTempDataset(java.lang.String writeTempDataset)
```
    Temporary dataset. When writing to BigQuery from large file loads, the BigQueryIO.write() will create temporary tables in a dataset to store staging data from partitions. With this option, you can set an existing dataset to create the temporary tables. BigQueryIO will create temporary tables in that dataset, and will remove it once it is not needed. No other tables in the dataset will be modified. Remember that the dataset must exist and your job needs permissions to create and remove tables inside that dataset.
  - withErrorHandler
```
public BigQueryIO.Write<T> withErrorHandler(ErrorHandler<BadRecord,?> errorHandler)
```
  - validate
```
public void validate(PipelineOptions pipelineOptions)
```
    Description copied from class: PTransform
    
    Called before running the Pipeline to verify this transform is fully and correctly specified.
    By default, does nothing.
    
    Overrides:
    
    validate in class PTransform<PCollection<T>,WriteResult>
  - expand
```
public WriteResult expand(PCollection<T> input)
```
    Description copied from class: PTransform
    
    Override this method to specify how this PTransform should be expanded on the given InputT.
    NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.
    Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
    
    Specified by:
    
    expand in class PTransform<PCollection<T>,WriteResult>
  - populateDisplayData
```
public void populateDisplayData(DisplayData.Builder builder)
```
    Description copied from class: PTransform
    
    Register display data for the given transform or component.
    populateDisplayData(DisplayData.Builder) is invoked by Pipeline runners to collect display data via DisplayData.from(HasDisplayData). Implementations may call super.populateDisplayData(builder) in order to register display data in the current namespace, but should otherwise use subcomponent.populateDisplayData(builder) to use the namespace of the subcomponent.
    By default, does not register any display data. Implementors may override this method to provide their own display data.
    
    Specified by:
    
    populateDisplayData in interface HasDisplayData
    
    Overrides:
    
    populateDisplayData in class PTransform<PCollection<T>,WriteResult>
    
    Parameters:
    
    builder - The builder to populate with display data.
    
    See Also:
    
    HasDisplayData
  - getTable
```
public @Nullable ValueProvider<TableReference> getTable()
```
    Returns the table reference, or null.
