Some bugs and spring pilgrimage to Percona Live Santa Clara 2018

I am now in an airport, waiting for one of the four flights that will bring me to Percona Live Santa Clara 2018.  This is a good time to write some details about my tutorial on parallel replication.  But before talking about Percona Live, I will share thoughts on MySQL/MariaDB bugs that caught my attention in the last weeks/months (Valeriy: you clearly have an influence on me).

MySQL/MariaDB

Next week in Brussels: Parallel Replication at the MySQL Pre-FOSDEM Day

FOSDEM is next weekend and I am talking about Parallel Replication on Friday, February 2nd at the MySQL Pre-FOSDEM Day (there might be tickets left in case of cancellation, attendance is free of charge).  During this talk, I will show benchmark results of MySQL 8.0 parallel replication on Booking.com real production environments.  I thought I could share a few things before the talk so here it

Write Set in MySQL 5.7: Group Replication

In my previous post, I write that Write Set is not only in MySQL 8.0 but also in MySQL 5.7 though a little hidden.  In this post, I describe Write Set in 5.7 and this will bring us in the inner-working of Group Replication.  I am also using this opportunity to explain and show why members of a group can replicate faster than a standard slave.  We will also see the impacts, on Group Replication,

An update on Write Set (parallel replication) bug fix in MySQL 8.0

In my MySQL Parallel Replication session at Percona Live Santa Clara 2017, I talked about a bug in Write Set tracking for parallel replication (Bug#86078).  At the time, I did not fully understand what was going wrong but since then, we (Engineers at Oracle and me) understood what happened and the bug is supposed to be fixed in MySQL 8.0.4.  This journey thought me interesting MySQL behavior and

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 Booking.com 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 Booking.com without looking at MySQL (Thursday keynote) The two little bugs that almost brought down Booking.com (Tuesday Lightning Talk) MySQL/MariaDB Parallel Replication: inventory, use cases and

Booking.com talks at Percona Live Santa Clara 2017

In a week, me and some Booking.com colleagues will be in Santa Clara for Percona Live.

Booking.com 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 “

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

Parallel Replication: Post on Booking.com Blog, Talk at Percona Live Amsterdam 2016, and more

I have a new blog post on blog.booking.com describing MariaDB 10.1 Optimistic Parallel Replication (with benchmark results):

Let's meet at Percona Live Amsterdam

I am very happy that my talk, MySQL Parallel Replication: inventory, use-cases and limitations, is included in the Sneak Peek of Percona Live Amsterdam.  As a member of the Conference Committee, I knew this was being discussed, but I refrained from commenting on discussion about my talk and the submissions of my colleagues from Booking.com.

Mentioning the conference committee, as you can guess,
