Join 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.

Releases

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.

Link List

• FOSDEM MySQL and Friends DevRoom call for papers closes December 1, 2017.
• MongoDB is now public, and the stock was up. Congratulations to all my friends there, and I can only imagine how becoming a public company will lead to more exciting times for MongoDB.
• Why we built our own distributed column store by Sam Stokes – very interesting talk by our friends at Honeycomb.io.
• Following on from last week, ACID transactions in a globally distributed database.
• James Turnbull has an excellent introduction to Prometheus.

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!
