Questions tagged [delayed-job]

A Ruby library to queue and defer processing of slow methods like sending email and image resizing.

Delayed_job (or DJ) encapsulates the common pattern of asynchronously executing longer tasks in the background.

Amongst those tasks are: •sending massive newsletters •image resizing •http downloads •updating smart collections •updating solr, our search server, after product changes •batch imports •spam checks
