Up to now, the way of updating dbdeployer was the same as installing it for the first time, i.e. looking at the releases page, downloading the binaries for your operating system, unpacking it and finally replacing the existing binaries.

This is not the procedure I follow, however, as for me updating means just compile the latest version I have just finished coding. For this reason, when Simon Mudd mentioned to me that dbdeployer should update itself over the Internet, I didn’t immediately grasp the concept. But then …

This title may be suitable for the new age MySQL Users. Because in 5.7 onwards its already supported to enable GTID online. But still few of my mission critical databases are in 5.6 and handling 70k QPS. So I know enabling GTID needs downtime for this. But in my case, the GTID has been already implemented. But still the replication is using Binlog file name and position for replicating the data.

This is my slave status. You can see the GTID has been enabled but the Auto_Position is still 0 which means still my replication is binlog filename and position. No issues with the replication. But the MySQL world already moved to GTID for better control on replication and Failover.

Earlier I wrote about check constraints when MySQL 8.0.16 was released. But this week I noticed two different folks having similar problems with them. And sadly it is 'pilot error'.

The first was labeled  MYSQL 8.0.17 CHECK not working even though it has been implemented and a cursory glance may make one wonder what is going on with the database.

The table is set up with two constraints. And old timers will probably mutter something under their breath about using ENUMs but here they are:

 JOB_TITLE varchar(20) CHECK(JOB_TITLE IN ('Lecturer', 'Professor', 'Asst. Professor', 'Sr. Lecturer')),

Do you want to run Galera Cluster in the Microsoft cloud? Why not learn to setup a 3-node Galera Cluster using Microsoft Azure Compute Virtual Machines, and run it yourself. In this webinar, we will cover the steps to do this, with a demonstration of how easy it is for you to do.

In addition, we will cover why you may want to run a 3-node (or more) Galera Cluster (active-active multi-master clusters) instead of (or in addition to) using Azure Database for MySQL or MariaDB. We will also cover cost comparisons. 

Join us and learn about storage options, backup & recovery, as well as monitoring & metrics options for the “roll your own Galera Cluster” in Azure.

The monitoring of IT systems is an important practice that should be in place in any complex computing environment. It provides a window into the inner-workings of the systems and applications with which a business or organization operates. The statistics produced by a monitoring platform can be used to optimize systems, enhance the user experience or plan for capacity upgrades.

A viable monitoring platform is designed with the ability to generate and send alerts. This feature increases the utility of the tool by introducing the possibility of creating immediate notifications to address potential issues or inconsistencies in the systems being observed. Alerts are routed to individuals or teams who can take action to further investigate or resolve the problems. Let’s take a closer look at why you want alerts to be created and how your organization should handle them.

ProxySQL 2.0.6, released by ProxySQL, is now available for download in the Percona Repository along with Percona’s proxysql-admin tool.

ProxySQL is a high-performance proxy, currently for MySQL and database servers in the MySQL ecosystem (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. René Cannaò created ProxySQL for DBAs as a means of solving complex replication topology issues.

This release includes ProxySQL 2.0.6 which introduces many new features and enhancements and also …

Excellent….Work like charm !!!

One of the perks of working on MySQL is that the code can compile (and has been compiled) on pretty much all of the modern (and no so modern) C/C++ compilers and all the modern OSes. This enables each individual developer to choose their “weapon”: pick the OS and the compiler they feel best about.…
