Percona Live Europe Amsterdam Day 1 notes

Percona Live Europe Amsterdam Day 1 was a bunch of fun, especially since I didn’t have to give a talk or anything since my tutorial was over on Day 0.

At lunch, I realised that there are a lot more fringe events happening around Percona Live… and if you’ve seen how people do “tech weeks”, maybe this is what the event ends up being – a show, plus plenty of focused satellite events. FOSDEM in the open source world totally gets this, and best of all, also lists fringe events (see example from 2019).

So, Thursday evening gets a few fringe events, a relatively short train ride away:

Minimalist Tooling for MySQL/MariaDB DBAs

In my roles as a DBA at various companies, I generally found the tooling to be quite lacking. Everything from metrics collection, alerting, backup management; they were either missing, incomplete or implemented poorly. DBA-Tools was born from a desire to build backup tools that supported my needs in smaller/non-cloud environments. As BASH is easily the most common shell available out there on systems running MySQL® or MariaDB®, it was an easy choice.

How DBA-Tools came to be

While rebuilding my home-lab two years ago, I decided I wanted some simple tools for my database environment. Being a fan of NOT re-inventing the wheel, I thought I would peruse GitHub and Gitlab to see what others have put together. Nothing I saw looked quite like what I wanted. They all hit one or more of the checkboxes I wanted, but never all of them.

My checklist when searching …

Fun with Bugs #88 - On MySQL Bug Reports I am Subscribed to, Part XXII

It's Saturday night. I have a week of vacation ahead that I am going to spend at home, working on things I usually do not have time for. I already did something useful (created a couple of test cases for MariaDB bugs here and there, among other things), so why not to get some fun and continue my previous review of recent interesting MySQL bug report...

So, here is the list of 15 more MySQL community bug reports that I've subscribed to back in May and June 2019:

  • Bug #95491 - "The unused wake up in simulator AIO of function reserve_slot". I am impressed by …

MySQL 5.6/Maria 10.1 : How we got from 30k qps to 101k qps…..

Late one evening, I was staring at one of our large MySQL installations and noticed the database was hovering around 7-10 run queue length (48 cores, ~500 gigs memory, fusionIO cards). I had been scratching my head on how to get more throughput from the database. This blog records the changes I made to tune performance in order to achieve a 300% better throughput in MySQL. I tested my theories on MySQL 5.6/Maria 10.1. While with 5.7 DBAs would turn to performance_schema for the supporting metrics, I hope that you find the process interesting nevertheless.

View from an Oracle RDBMS DBA…

For context, I came to MySQL from a background as an Oracle RDBMS DBA, and this informs my expectations. For this exercise, unlike with Oracle RDBMS, I had no access to view wait events so that I could see where my database was struggling. At least, no access in MySQL 5.6/Maria 10.1 without taking a performance hit by using …

Blog from the Top — What keeps you up at night? Sleep better with Continuent!

Database Administration is a tough, often ungrateful job. Especially if you run a 24/7 business-critical MySQL or MariaDB deployment.

MySQL has proven to be a remarkably solid database which supports billions of dollars in revenue. On some level this very solidity creates a false sense of security. There are many things that can wrong at any given time, whether that is a change to your app, a bug in the database, hardware failure or just simply running out of disk space.

Percona recently conducted a poll: “What keeps you up at night?”

Not surprisingly, “Downtime/HA” is very high on the list.

While there are many challenging issues and tasks that a DBA must deal …
