Given an environment where a high volume web application is prone to opening many connections to backend resources, using a utility like pt-stalk is important. When performance or availability affecting events like innodb lock waits or connection saturation occur, pt-stalk helps give you information you may need in troubleshooting what was happening.
The tendency may be to create multiple pt-stalks for various conditions. This can be a poor decision when your server is dealing with both lock contention and high connections. When pt-stalk triggers, it …[Read more]

So, if we’re applying GDPR to our system, and we’re already making use of MySQL Transparent Data Encryption / keyring, then here’s an example on how to migrate from filed-based keyring to the encrypted keyring. Online.
If you’re looking to go deeper into the TDE then I suggest reading the MySQL Server Team’s InnoDB Transparent Tablespace Encryption blog.
You’d already have your environment running, whereas I have to create one.. give me a minute please, 8.0.12 here we come:
mysqld --defaults-file=my_okv.cnf --initialize-insecure --user=khollman mysqld --defaults-file=my_okv.cnf --user=khollman & mysql …[Read more]
In a previous blog, I discussed how to pull, install and run MySQL 8.0 with Docker. I showed how to connect to the Docker daemon with MySQL.
Now I will show you how to connect to the same Docker instance using the MySQL Shell which is a tool to use Document Store and to create InnoDB Clusters.
Installing Docker, Starting MySQL, and Connecting using MySQL Shell
First, you grab Docker: https://docs.docker.com/install .
Then, you pull and run MySQL 8.0 (Linux) by running the following. Note that I’m not using a password which is just for testing a fleeting MySQL Docker container:
$ docker run –name mysql8 -e MYSQL_ALLOW_EMPTY_PASSWORD=yes -d mysql/mysql-server
Unable to find image ‘mysql/mysql-server:latest’ locally
When I worked at Borland on InterBase (one of the first MVCC relational databases), the saxophone-playing founder of Borland, Philippe Kahn, would talk about the ‘forehead install’ at nearly every meeting that I attended. Installs should be easy, he would say. As easy as hitting your forehead to the space bar. In fact, Kahn claimed that installing software with another product “could be equivalent to a heart transplant”.
Although MySQL installs are not complex, there is one tool that can make installs and test driving new software more palatable – Docker.
There are two advantages of testing MySQL 8.0 with Docker: (1) installing and starting MySQL 8.0 is even simplier with Docker and (2) changing my.cnf values with the SET PERSIST option can also help you navigate the Docker environment.
Installing Docker, Starting MySQL, and Connecting to MySQL
First, you grab Docker: …[Read more]
In another post, I explained how to use the MySQL Query Re-write Plugin to manipulate data that didn’t exactly match SQL standards of MySQL. In this post, I am going to give you another example on how to use a trigger to parse non-conforming data so the data can be written to a MySQL database.
A customer came to me with a problem. They were using third-party software which produced multiple rows of comma-separated data (like a .csv file), but all of the data wasn’t on a single row. Instead, the data consisted of multiple rows of data, separated by commas and with line feeds after each row of data. Here …[Read more]

The MySQL database is used in thousands of third-party applications, but what can you do when you want to use MySQL with an application, but that application’s queries or data doesn’t match MySQL’s data type or SQL format?
This post will show you three ways to alter a query or mismatched data when you don’t have control of the application’s source code. Of course, there are hundreds of different ways to do what I am about to show you. In this example, I will show you how to use the MySQL Query Rewrite Plugin along with a trigger to alter the non-conforming data. I will also show you an example of manipulating data with a stored procedure.
A customer emailed me with a problem. They wanted to use …[Read more]
It can be hard to recall all the details of how a program and API work. The usual way to handle that is to look at the manual or a book. Another – and in my opinion – nice way is to have built-in help, so you can find the information without changing between the program and browser. This blog discuss how to obtain help when you use MySQL Shell.
