Jon and myself (Gerry) both work at MariaDB, but we intend to keep this show independent, covering all MySQL and MariaDB Community spaces with a focus on Open Source. The show is an offspring of the OurSQL Community Podcast, which was kindly sponsored by Oracle and allowed us to remain content independent. We are committed to keep that tradition.

On this first episode we introduce the show and it's new format and talk about High Availability. The schedule is intended to be monthly, although it'll be more frequent in the beginning to publish all the episodes that we have already recorded.

We are currently sponsored by MariaDB Corp.
