Method Detail

create

public static BigQueryReader create(Scope scope,
                                    String projectId,
                                    String datasetId,
                                    String tableId,
                                    List<String> columns,
                                    Long timestampMillis,
                                    BigQueryReader.Options... options)

Factory method to create a class wrapping a new BigQueryReader operation.

Parameters:

scope - current scope

projectId - GCP project ID.

datasetId - BigQuery Dataset ID.

tableId - Table to read.

columns - List of columns to read. Leave empty to read all columns.

timestampMillis - Table snapshot timestamp in millis since epoch. Relative (negative or zero) snapshot times are not allowed. For more details, see 'Table Decorators' in BigQuery docs.

options - carries optional attributes values

Returns:

a new instance of BigQueryReader

container

public static BigQueryReader.Options container(String container)

Parameters:

container - If non-empty, this reader is placed in the given container. Otherwise, a default container is used.

sharedName

public static BigQueryReader.Options sharedName(String sharedName)

Parameters:

sharedName - If non-empty, this reader is named in the given bucket with this shared_name. Otherwise, the node name is used instead.

testEndPoint

public static BigQueryReader.Options testEndPoint(String testEndPoint)

Parameters:

testEndPoint - Do not use. For testing purposes only.

readerHandle

public Output<String> readerHandle()

The handle to reference the Reader.

asOutput

public Output<String> asOutput()

Description copied from interface: Operand

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

Specified by:

asOutput in interface Operand<String>
