createTransformation
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 withProviderContext.generateUid(String)
