My two parallel replication talks at Percona Live Santa Clara 2017

Yes, another post about my talks at Percona Live Santa Clara: I obviously still have things to share.  This time, I will focus on my parallel replication talks by giving a short preview.

I have two parallel replication talks at Percona Live:

MySQL/MariaDB Parallel Replication: inventory, use cases and limitations (Wednesday talk) MySQL Parallel Replication: all the 5.7 (and some of the 8.0)

My talks at Percona Live Santa Clara 2017

In a previous post, I listed all the talks at Percona Live.  In this post, I will give more details about my talks.

As a reminder, the list of my talks is the following:

Monitoring without looking at MySQL (Thursday keynote) The two little bugs that almost brought down (Tuesday Lightning Talk) MySQL/MariaDB Parallel Replication: inventory, use cases and talks at Percona Live Santa Clara 2017

In a week, me and some colleagues will be in Santa Clara for Percona Live. is sponsoring the conference and we will be present at the Monday Evening Reception.  You do not need a tutorial pass to attend the dinner (even if it is on the tutorial day): any valid pass will do.  If you do not have your ticket yet, it is time to register (you can use the discount code “

Busy April 2017: MariaDB Dev Meeting (no-slave-left-behind, MyRocks, ...) and Percona Live

In a few days, I will start my yearly travel to North America which will bring me at Percona Live at the end of the month.  But I will first stop in New York to attend the MariaDB Developer Meeting.  Let's see what will happen there.

Percona Live is sponsoring the conference, and we will be present at the Monday Evening Reception.  You do not need a tutorial pass to attend: any

Better InnoDB Crash Recovery in MariaDB 10.1

Recently, I had to go through crash recovery of a large MariaDB 10.1.21 instance.  After starting MariaDB, I started tailing the error logs expecting to wait many minutes while InnoDB was scanning ibd files.  I was surprised (and actually delighted) with this:

[...] [...]:34:36 [...] [Note] InnoDB: Reading tablespace information from the .ibd files... [...]:34:53 [...] [Note] InnoDB: Processed

A Metric for Tuning Parallel Replication in MySQL 5.7

MySQL 5.7 introduced the LOGICAL_CLOCK type of multi-threaded slave (MTS).  When using this type of parallel replication (and when slave_parallel_workers is greater than zero), slaves use information from the binary logs (written by the master) to run transactions in parallel.  However, enabling parallel replication on slaves might not be enough to get a higher replication throughput (VividCortex

Tab Sweep – MySQL ecosystem edition

Tab housekeeping but I also realise that people seem to have missed announcements, developments, etc. that have happened in the last couple of months (and boy have they been exciting). I think we definitely need something like the now-defunct MySQL Newsletter (and no, DB Weekly or NoSQL Weekly just don’t seem to cut it for me!).


During @scale (August 31), Yoshinori Matsunobu mentioned that MyRocks has been deployed in one region for 5% of its production workload at Facebook.

By October 4 at the …

Debian and MariaDB Server

GNU/Linux distributions matter, and Debian is one of the most popular ones out there in terms of user base. Its an interesting time as MariaDB Server becomes more divergent compared to upstream MySQL, and people go about choosing default providers of the database.

The MariaDB Server original goals were to be a drop-in replacement. In fact this is how its described (“It is an enhanced, drop-in replacement for MySQL”). We all know that its becoming increasingly hard for that line to be used these days.

Anyhow in March 2016, Debian’s release team has made the decision that going forward, MariaDB Server is what people using …

FOSDEM 2016 notes

While being on the committee for the FOSDEM MySQL & friends devroom, I didn’t speak at that devroom (instead I spoke at the distributions devroom). But when I had time to pop in, I did take some notes on sessions that were interesting to me, so here are the notes. I really did enjoy Yoshinori Matsunobu’s session (out of the devroom) on RocksDB and MyRocks and I highly recommend you to watch the video as the notes can’t be very complete without the great explanation available in the slide deck. Anyway there are videos from the MySQL and friends devroom.

Speaking in April 2016

I have a few speaking engagements coming up in April 2016, and I hope to see you at some of these events. I’m always available to talk shop (opensource, MariaDB Server, MySQL, etc.) so looking forward to saying hi.

  • A short talk at the MariaDB Berlin Meetup on April 12 2016 – this should be fun if you’re in Berlin as you’ll see many people from the MariaDB Server and MariaDB MaxScale world talk about what they’re doing for the next releases.
  • – April 14-15 2016, tutorial day on 16 – I’ve not been to India since about 2011, so I’m looking forward to this trip to Bangalore (and my first time to a HasGeek event). Getting the email from the conference chair was very nice, and I believe I’m giving a keynote and a tutorial.
