RequestList

Represents a (potentially very large) list of URLs to crawl.

Disclaimer: The RequestList class is in its early version and is not fully implemented. It is currently intended mainly for testing purposes and small-scale projects. The current implementation is only in-memory storage and is very limited. It will be (re)implemented in the future. For more details, see the GitHub issue: https://github.com/apify/crawlee-python/issues/99. For production usage we recommend to use the RequestQueue.
