Real-time web scraping multiple websites

I need a solution for extraction data in "near real time" from different websites but with the same general topic.

I don't know the numbers of starting pages (maybe 500.000)

The software should do:

- Autodiscovery new URLs (based on specific rules)

- Extract and save some particular data (object name, description, price, ...) and general data (HTML title, author, ...)

- These data must be updated continuously

- These data should be saved in a database

- I need a JSON API that should inquiry that database with these functionalities

- parametric search

- aggregate search

- full-text search

- In case of error or new needs, It should be reprocessed all or some pages.

- Easy to add new sites.

- Enable to scrape ajax based websites.

I'd like to have a solution that can be easy to install, configure and most of all easy to update in case of errors.

Compétences : AJAX, JSON, Web Scraping
