In this episode of Elixir Mix the panel interviews Parker Selbert. Parker lives in Chicago and runs a consultancy with his wife. He joins the panel to discuss a library that he wrote, Oban. Parker starts by explaining what Oban is and why he wrote it. Oban is a way to run reliable background jobs by persisting them in the database. Oban is akin to Sidekick, Parker explains, he wanted something similar to Sidekick for Elixir. He made a few improvements including moving it to Postgres from Redis. He shares the common problems found using Redis and how easy Postgres was to use for this library.  The panel asks Parker about his Oban Recipes. Parker explains why he wrote the recipes and what some of them contain. After releasing Oban he received many questions asking about how to use Oban. Parker took the most common questions and wrote 7 blog post outlining how to use Oban.  Parker shares his favorite features found in Oban and walks the panel through its architecture. The panel asks him about the maturity and usage of the library. Parker tells them that the usage has been steadily climbing. The episode ends with the panel discussing the Oban UI and how it works.   Panelists
