At Percona Live Amsterdam recently, the conference expanded beyond just its focus areas of MySQL & its ecosystem and MongoDB to also include PostgreSQL and other open source databases (just look at the recent poll). The event was a sold out success.
This will continue for Percona Live Santa Clara 2017, happening April 24-27 2017 – and the call for papers is open till November 13 2016, so what are you waiting for? Submit already!
I am on the conference committee and am looking forward to making the best program possible. Looking forward to your submissions!
