Method Details

createTransformation

org.apache.flink.api.dag.Transformation<?> createTransformation(TransformationSinkProvider.Context context)

Creates a transformation for transforming the input provided in the context.

Note: If the CompiledPlan feature should be supported, this method MUST set a unique identifier for each transformation/operator in the data stream. This enables stateful Flink version upgrades for streaming jobs. The identifier is used to map state back from a savepoint to an actual operator in the topology. The framework can generate topology-wide unique identifiers with ProviderContext.generateUid(String).
