About a month ago, I published how you can connect to MySQL with a small form. One suggestion, or lets promote it to a request, from that post was: “Nice, but how do you create a reusable library for the MySQL Connection Dialog box?”

That was a good question but I couldn’t get back until now to write a new blog post. This reusable MySQL connection dialog lets you remove MySQL connection data from the command-line history. This post also shows you how to create and test a Powershell Module.

The first step to create a module requires that you set the proper %PSModulePath% environment variable. If you fail to do that, you can put it into a default PowerShell module location but that’s not too effective for testing. You launch the System Properties dialog and click the Environment …

MySQL is a widely-used open source relational database management system. In this tutorial, we will use one master node to store the cluster's configuration and two data nodes to store the cluster data.

Back in December 2018, when we announced the general availability of Percona Server for MySQL 8.0, we also announced that the TokuDB Storage Engine has been marked as “deprecated” in this release, recommending to use the MyRocks Storage Engine as an alternative. We believe that MyRocks provides similar benefits for the majority of workloads and is better optimized for modern hardware.

Since then, we have continued maintaining the storage engine in the 8.0 release, e.g. by incorporating bug fixes. However, the ongoing amount of …

To see what queries are sent to MySQL, it’s useful to enable query logging and piping the output to a file or even a table to inspect later. In this [...]

One of the problems that comes with age is that there is so much 'baggage' filling valuable brain area that it sometimes requires a mental sweeping before trying to learn a new skill. I am still getting rid of FORTRAN and COBOL factoids but need to come up to speed on extending MySQL for some talks I am giving.  So away with the PROCEDURE DIVISION stuff... 

The MySQL Shell or Mysqlsh is very extensible and it is easy to create a plugin for some handy routines.  Your routines can go in functions and there are examples below.  The tricky part is that you have to tell Mysqlsh that you are creating an extension and then hook up your function(s) to that extension object. Finally that extension object has to be registered with the shell.

So below are two functions which query the MySQL World Database for the contents of the world.city and the world.country tables.  The first thing for both of these …

Percona Server for MySQL 8.0.23-14 was released last week and I wanted to take a minute to call out some of the interesting new features that we have introduced in this release. These are included in addition to the features and improvements in MySQL 8.0.23 that were introduced by the Oracle MySQL team (and to which Percona also contributed).

 As introduced in a previous blog RonDB enables us to easily execute benchmarks on RonDB using the Sysbench benchmark.

In this blog I will present some results where the RonDB cluster had 2 data nodes, each using a r5.4xlarge VM in AWS that has 16 VCPUs and 128 GB memory. The Sysbench test uses SQL to access RonDB.

In this particular test case we wanted to test the Key-Lookup performance using SQL. Key-Lookup performance is essential in the RonDB use case as an online Feature Store in Hopsworks.

In this case we use the …
