I’m using Python with Celery and RabbitMQ to make a web spider to count the number of links on a page.
Can a database, such as MySQL, be written into asynchronously? Is it OK to commit the changes after every row added, or is it required to batch them (multi-add) and then commit after a certain number of rows/duration?
I’d prefer to use SQLAlchemy and MySQL, unless there is a more recommended combination for Celery/RabbitMQ. I also see NoSQL (CouchDB?) recommended.
For write intensive operation like Counters and Logs NoSQL solution are always the best choice. Personally I use a mongoDB for this kind of tasks.
