The output fields of a Chunking transformation include a ChunkedText field that stores the chunks and a ProcessedText field that stores the processed text. If the Chunking transformations performs both chunking and text processing, the ProcessedText field stores the output after applying text processing functions to the chunks.
As an active transformation, the Chunking transformation delivers an output that's usually equal to or more than the number of rows you input into the transformation. Empty or null rows aren't factored into the splitting methods and don't appear in the ChunkedText field.
You can pass the output fields to a Vector Embedding transformation to generate vector embeddings. If the Chunking transformation performs both chunking and text processing, use ProcessedText to generate vector embeddings. However, you should also pass ChunkedText to the downstream Vector Embedding and Target transformations and include the chunks in the vector embedding metadata that's inserted into the vector database.
