“Why is a database rarely the best tool for a queue based problem”

Lovisa Johanson posted an article on the CloudAMQP blog which is a useful read in case that you enjoyed my two articles about Firebird Database Events and Message-oriented Middleware (part 1, part 2) on the Habari! blog.

It is based on a simple user scenario:

  1. Customer uploads a text document
  2. Your application converts the text document into a PDF
  3. Your application emails the PDF back to the customer

The article illustrates the limitations that you might notice if you use a database for a queue based system, and describes why using a message queue is recommended when you need to process a high-volume of asynchronous messages.
