    A chunk of data from a streaming query result.

    DataChunks contain a fixed number of rows and provide methods to access the data in various formats.

    for await (const chunk of stream) {
      console.log(`Chunk has ${chunk.rowCount} rows`);

      // Get as array of objects
      for (const row of chunk.toArray()) {
        console.log(row);
      }

      // Or access raw columnar data
      const column = chunk.getColumn(0);
      console.log(column);
    }
