Class BigtableIO.Write

    • 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 cluster 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 cluster 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.

      • getBigtableOptions

        public com.google.cloud.bigtable.config.BigtableOptions getBigtableOptions()
        Returns the Google Cloud Bigtable cluster being written to, and other parameters.
      • getTableId

        public String getTableId()
        Returns the table being written to.
      • apply

        public PDone apply(PCollection<KV<com.google.protobuf.ByteString,Iterable<com.google.bigtable.v1.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).

        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<InputT, OutputT>, InputT).

        Overrides:
        apply in class PTransform<PCollection<KV<com.google.protobuf.ByteString,Iterable<com.google.bigtable.v1.Mutation>>>,PDone>
      • validate

        public void validate(PCollection<KV<com.google.protobuf.ByteString,Iterable<com.google.bigtable.v1.Mutation>>> input)
        Description copied from class: PTransform
        Called before invoking apply (which may be intercepted by the runner) to verify this transform is fully specified and applicable to the specified input.

        By default, does nothing.

        Overrides:
        validate in class PTransform<PCollection<KV<com.google.protobuf.ByteString,Iterable<com.google.bigtable.v1.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,Iterable<com.google.bigtable.v1.Mutation>>>,PDone>
        Parameters:
        builder - The builder to populate with display data.

        HasDisplayData
