Method Detail

named

public BigQueryIO.Write.Bound named(java.lang.String name)

Sets the name associated with this transformation.

to

public BigQueryIO.Write.Bound to(java.lang.String tableSpec)

Specifies the table specification.

Refer to BigQueryIO.parseTableSpec(String) for the specification format.

to

public BigQueryIO.Write.Bound to(TableReference table)

Specifies the table to be written to.

withSchema

public BigQueryIO.Write.Bound withSchema(TableSchema schema)

Specifies the table schema, used if the table is created.

withCreateDisposition

public BigQueryIO.Write.Bound withCreateDisposition(BigQueryIO.Write.CreateDisposition createDisposition)

Specifies options for creating the table.

withWriteDisposition

public BigQueryIO.Write.Bound withWriteDisposition(BigQueryIO.Write.WriteDisposition writeDisposition)

Specifies options for writing the table.

withoutValidation

public BigQueryIO.Write.Bound withoutValidation()

Disable table validation.

apply

public PDone apply(PCollection<TableRow> input)

Description copied from class: PTransform

Applies this PTransform on the given Input, and returns its Output.

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).

The default implementation throws an exception. A derived class must either implement apply, or else each runner must supply a custom implementation via PipelineRunner.apply(com.google.cloud.dataflow.sdk.transforms.PTransform<Input, Output>, Input).

Overrides:

apply in class PTransform<PCollection<TableRow>,PDone>

getDefaultOutputCoder

protected Coder<java.lang.Void> getDefaultOutputCoder()

Description copied from class: PTransform

Returns the default Coder to use for the output of this single-output PTransform, or null if none can be inferred.

By default, returns null.

Overrides:

getDefaultOutputCoder in class PTransform<PCollection<TableRow>,PDone>

getKindString

protected java.lang.String getKindString()

Description copied from class: PTransform

Returns a string describing what kind of PTransform this is.

By default, returns the base name of this PTransform's class.

Overrides:

getKindString in class PTransform<PCollection<TableRow>,PDone>

getCreateDisposition

public BigQueryIO.Write.CreateDisposition getCreateDisposition()

Returns the create disposition.

getWriteDisposition

public BigQueryIO.Write.WriteDisposition getWriteDisposition()

Returns the write disposition.

getSchema

public TableSchema getSchema()

Returns the table schema.

getTable

public TableReference getTable()

Returns the table reference.

getValidate

public boolean getValidate()

Returns true if table validation is enabled.
