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 “

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 Blog, Talk at Percona Live Amsterdam 2016, and more

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

Evaluating MySQL Parallel Replication Part 4: More Benchmarks in Production

If you want to know more about MySQL/MariaDB Parallel Replication and if you are attending 

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

Mentioning the conference committee, as you can guess,

MySQL Parallel Replication and more talks at Percona Live (April 2016)

In a few days, I will be flying to San Francisco and then making my way to Santa Clara to attend the Percona Live Conference.  On the last day of the conference (Thursday), I will speak about MySQL Parallel Replication.  I hope to see you there and I will he happy to answer questions you might have (on this subject and others):

Thursday at 12:50 pm: MySQL Parallel Replication: inventory,

Replication crash safety with MTS in MySQL 5.6 and 5.7: reality or illusion?

Reminder: MTS = Multi-Threaded Slave.

Update 2017-04-17: since the publication of this post, many things happened:

the procedure for fixing a crashed slave has been automated (Bug#77496) Bug#80103 as been closed at the same time as Bug#77496 but I still think there are unfixed things, see Bug#81840

End of update 2017-04-17.

I will be talking about parallel replication at FOSDEM in Brussel on

JFG proposed sessions for Percona Live Santa Clara (and Community voting)

This year, Percona introduced Community Voting for Percona Live submission.  This is what you can read on the conference website:

In an effort to involve the larger community in the selection of speaking sessions for the 2016 Percona Live Data Performance Conference, we’ve implemented a community voting process. After a speaker submits a proposal we encourage sharing to the community and social

MariaDB 10.0 Parallel Replication Benchmark Results (and PLAMS and OOW).

My latest post is online on the blog: Evaluating MySQL Parallel Replication Part 3: Benchmarks in Production.  In this post, I present benchmark results on MariaDB 10.0 parallel replication on four production workloads.

This post is also the opportunity to promote my two talks at Percona Live Europe, taking place in Amsterdam from September 21 to 23:
