Presentation : Customer Experience on InnoDB Cluster

 

As Mydbops we have consulted  many large scale MySQL deployments. This presentation is about one of our customer who is one of the largest retailer in North America. This is about their data migration to InnoDB Cluster ( MySQL ) from an enterprise database.

Presentation : Handling Schema Changes Via Percona Toolkit

The schema changes in production can cause lock at time and makes the slave to lag. It is more tedious and troublesome with PXC ( Galera ) cluster which can be made smoother with Percona online schema change.

Why does the MySQL optimizer not do what I think it should?

In May, I presented two talks – one called “Are you getting the best out of your indexes?” and “Optimizing Queries Using EXPLAIN”. I now have slides and video for both of them.

The first talk about indexing should probably be titled “Why is MySQL doing this?!!?!!?” It gives insight into why the MySQL optimizer chooses indexes that you do not expect; especially when it does not use an index you expect it to.

The talk has something for everyone – for beginners it explains B-trees and how they work, and for the more seasoned DBA it explains concepts like average value group size, and how the optimizer uses those concepts applied to metadata to make decisions.

Slides are at http://technocation.org/files/doc/2017_05_MySQLindexes.pdf.

Lightning talks at Percona Live Amsterdam: come on stage!

The schedule to Percona Live Europe 2016 is being finalized. It should be published soon, and it will include 3 hour and 6 hour tutorials, regular 50-minute talks, and shorter 25-minutes talks. It will not include, however, the lightning talks, a session comprising several 5-minute talks, and they are missing from the initial schedule for two reasons:

  • We want to offer a chance to all attendees to propose a lightning talk for some time. We would like to have more quality material to choose from.
  • They will not be in the conference venue. Instead, they will be hosted at Booking, during the community dinner.

Unlike in previous editions, though, the lightning talks will …

MySQL and Docker on a Mac: networking oddity

This is a quick post only indirectly related to the series of articles about Docker that I have written recently.

Yesterday I was giving a presentation about Docker in Buenos Aires, and as usual I included a long live demo. Almost all went as expected. There was one step that I tried some time ago, and had always worked well, but when I tried to repeat it on stage, it failed miserably:

  • Step 1: run the container
$ docker run  -d --name mybox -e MYSQL_ROOT_PASSWORD=secret mysql/mysql-server …
