This Week in Data with Colin Charles 11: Velocity EU London and Open Source Summit Europe

Colin CharlesJoin Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

I spent all of this week at O’Reilly Velocity EU London. I gave a tutorial, a talk and generally networked with attendees (besides my normal evangelical duties). I’ll write some thoughts on it later (probably in a couple of weeks, as Open Source Summit Europe happens next week – and Percona has a booth there).

This will be a quick, short post.


A few security releases this past week, with some bug fixes as well:

  • MySQL 5.5.58 and the corresponding MariaDB Server 5.5.58, which include the CVE vulnerabilities fixes.
  • MySQL 5.6.38
  • MySQL 5.7.20 – I’d pay attention to the deprecated and removal notices. After all, the query cache is gone in 8.0 (this probably means that they can deprecate the query cache tuner Domas Mituzas built soon as well).
  • PMM 1.4.0 – In this release, Prometheus and Grafana have been upgraded. Prometheus version 1.7.2, shipped with this release, offers a number of bug fixes that will contribute to its smooth operation inside PMM.

Upcoming Appearances

  • Open Source Summit Europe – October 23-26, 2017, Prague, Czech Republic. Note that Percona has a booth at this show, so you can come by and say hello at any time!


I look forward to feedback/tips via e-mail at or on Twitter @bytebot.
