Problem Statement

#347 converts arrow array / RecordBatch reading from the LanceDataset to duckdb corresponding data structures via heavy data copy.

We need to implement zero-copy data transfer between arrow and duckdb to make the extension production ready.

  • Primitive Arrays to duckdb::Vector
  • ::arrow::StructArray
  • ::arrow::ListArray
  • ::arrow::DictionaryArray
