Interface StructuredDataflowAdapter

All Known Implementing Classes:

SparkFromJsonExplodeAdapter

public interface StructuredDataflowAdapter

Vendor-specific adapter that detects a structured-dataflow pattern (e.g. Spark explode(from_json(col, schema))) and returns a vendor-neutral StructuredDataflowDescriptor. Returning null means the adapter does not recognize the input, in which case existing lineage/IR behavior runs unchanged.

Method Detail

describe

StructuredDataflowDescriptor describe(TParseTreeNode node,
                                      StructuredAdapterContext context)

Returns:

descriptor if the adapter recognizes the pattern, else null.
