minion VS LANraragi

What finally drove me over the edge was writing some code for a client using the Minion job queue. The queue is solid, but it creates new database connections, thus ensuring that it can’t see anything in your database transactions. I figured out a (hackish) solution, but I was tired of hackish solutions.

Since Minion relies on PostrgeSQL the actual implementation was very simple. Just a few lines of Perl to spawn spare processes and one small change in the SQL query used to dequeue jobs.

Have you checked LANraragi? It can scrape the tags, language, artist, group, etc directly from EH and other sources.
