Method Detail

withBigtableOptions

public BigtableIO.Write withBigtableOptions(com.google.cloud.bigtable.config.BigtableOptions options)

Returns a new BigtableIO.Write that will write to the Cloud Bigtable instance indicated by the given options, and using any other specified customizations.

Does not modify this object.

withBigtableOptions

public BigtableIO.Write withBigtableOptions(com.google.cloud.bigtable.config.BigtableOptions.Builder optionsBuilder)

Returns a new BigtableIO.Write that will write to the Cloud Bigtable instance indicated by the given options, and using any other specified customizations.

Clones the given BigtableOptions builder so that any further changes will have no effect on the returned BigtableIO.Write.

Does not modify this object.

withTableId

public BigtableIO.Write withTableId(java.lang.String tableId)

Returns a new BigtableIO.Write that will write to the specified table.

Does not modify this object.

getBigtableOptions

public com.google.cloud.bigtable.config.BigtableOptions getBigtableOptions()

Returns the Google Cloud Bigtable instance being written to, and other parameters.

getTableId

public java.lang.String getTableId()

Returns the table being written to.

expand

public PDone expand(PCollection<KV<com.google.protobuf.ByteString,java.lang.Iterable<com.google.bigtable.v2.Mutation>>> input)

Description copied from class: PTransform

Applies this PTransform on the given InputT, 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).

Specified by:

expand in class PTransform<PCollection<KV<com.google.protobuf.ByteString,java.lang.Iterable<com.google.bigtable.v2.Mutation>>>,PDone>

validate

public void validate(PipelineOptions options)

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<KV<com.google.protobuf.ByteString,java.lang.Iterable<com.google.bigtable.v2.Mutation>>>,PDone>

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<KV<com.google.protobuf.ByteString,java.lang.Iterable<com.google.bigtable.v2.Mutation>>>,PDone>

Parameters:

builder - The builder to populate with display data.

HasDisplayData

toString

public java.lang.String toString()

Overrides:

toString in class PTransform<PCollection<KV<com.google.protobuf.ByteString,java.lang.Iterable<com.google.bigtable.v2.Mutation>>>,PDone>
