AirtableLoader

A method that loads the text file or blob and returns a promise that resolves to an array of Document instances. It reads the text from the file or blob using the readFile function from the node:fs/promises module or the text() method of the blob. It then parses the text using the parse() method and creates a Document instance for each parsed page. The metadata includes the source of the text (file path or blob) and, if there are multiple pages, the line number of each page.

Asynchronous generator function for lazily loading documents from Airtable. This method yields each document individually, enabling memory-efficient handling of large datasets by fetching records in pages.
