Document Read Blob
Description
Section titled “Description”The Document: Read Blob step reads whole documents into a base64 text column named Blob, with one row per document. Read one document you choose, or one document for each row of a table of paths. Later steps, such as Image OCR and Text NLP AI, read the content.
Source & Options
Section titled “Source & Options”- Table of document paths (optional) — set this to read one document for each row. Leave it blank to read the one document you choose.
- Path column — the column of that table that holds each document’s path.
- Document — the document account and path to read when there is no table.
- Fail when a document is missing — off by default. Off, a missing document is skipped with a warning that names its path, and a missing single document writes an empty table. On, the step fails.
- Largest document (bytes) (optional) — a larger document fails rather than being split.
- Output Table — where the rows are written.
Columns from the table of paths pass through to the output.
