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

Kristian Nielsen is working on a new feature for MariaDB 10.3 and he published very interesting results.  This feature is MDEV-12179: Per-engine mysql.gtid_slave_pos tables.  He writes about replicating twice as fast in the worst case when using two storage engines (InnoDB and MariaRocks in his tests, but could also be InnoDB and TokuDB or TokuDB and MyRocks).  I will let you read all the details

Welcome to the third (and final) day of the Percona Live Open Source Database Conference 2017, and the third (and final) set of Percona Live keynotes! The enthusiasm hasn’t waned here at Percona Live, and we had a full house on Thursday morning!

MySQL 8.0.1 is out and it includes an implementation of my feature request (Bug #77438).  This extension to RESET MASTER allows to simplify master promotion with Binlog Servers.  Let's see how it works:

# mysql -N <<< "SHOW MASTER STATUS" binlog.027892 3006935 # mysql -N <<< "RESET MASTER TO 12345; DO sleep(rand()*10); SHOW MASTER STATUS" binlog.012345 92773 # mysql -N <<< "RESET MASTER TO

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.
