If you use replication with MySQL, if you need a backup, if you need a spare copy of a system for testing and for many other reasons you need a way to make a copy of your MySQL system. In the past you could make a copy in various ways: using a cold file system … Continue reading MySQL 8.0.17+: Cloning is now much easier

Overview The Skinny

In this blog post, we explore the correct way to implement bi-directional Tungsten Replication between AWS Aurora and Tungsten Clustering for MySQL databases.

Background The Story

When we are approached by a prospect interested in using our solutions, we are proud of our pre-sales process by which that we engage at a very deep technical level to ensure the we provide the best possible solution to meet with the prospect’s requirements. This involves an in-depth hands-on POC, in addition to the significant time and effort we spend building and testing the solution architectures in our lab environment as part of the proposal process.

From time to time, we are presented with requirements that are not always quite so straight forward. Just recently we faced such a situation. A …

Last week I posted a blog on how to setup multi-source for MySQL 5.7 using GTID based replication, in this blog we will do the same using MySQL 8.0.

Most of the procedure are the same, there are only two things that we need to change are;
1) Procedure for creating the replication user.
2) Fetching the GTID value from the MySQL dumpfile.

1) Create replication user for MySQL 8
MySQL 8 uses a new authentication plugin so to create the replication user will differ from MySQL 5.7. The procedure for 5.7 was with:

mysql> CREATE USER 'repl_user'@'slave-host' IDENTIFIED BY 'repl_pass';
mysql> GRANT REPLICATION SLAVE ON *.* TO 'repl_user'@'slave-host';

With MySQL 8 you need to create the user like:

mysql> CREATE USER …

Up to MySQL 8.0.16, to perform these tasks you could:
- Use MySQL Enterprise Backup :
- Use mysqldump

Starting with MySQL 8.0.17, the easiest and recommended method is to use the CLONE feature.

Oracle Code One starts September 16th and the MySQL Track is packed with interesting presentations. The session coded that start with 'DEV' are general talks. Hands on Labs start with 'HOL' and you will have a pre imaged laptop to use to do the lab work. And 'TUT' is for tutorials.  Use the mobile OOW/CodeOne app to reserve your space as space is limited and there is limited stand by space.

I highly recommend the State of the Dolphin talk on Monday as that will provide the richest overview of what is going on within the MySQL Community.

And Tuesday night is the traditional MySQL Community Reception from 7-9:00 PM at the Samovar Wine Bar which is open to all.

On October 3rd ProxySQL will have it’s very first technology day. They have chosen the lovely city of Ghent, Belgium, my home town, as the place to be. For those attending Percona Live Europe in Amsterdam, this is a great opportunity to extend your stay for a bit and take a two-hour train ride from the Percona Live venue at Amsterdam airport to Ghent where you can get some additional ProxySQL-specific content.

The ProxySQL team has selected a few experienced speakers to come and talk about their product. Vlad Fedorkov from ProxySQL LLC will have two sessions. The first one will be about High Performance MySQL and the second one will be about traffic management and performance troubleshooting.
