Advice on pt-stalk for connection saturated servers

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 …

MySQL TDE: Online key store migration

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:

Running MySQL Shell 8.0 with Docker

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

Driving Innovation with MySQL 8.0 and Docker

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:  …

Using a trigger to parse non-conforming data in MySQL

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 …

MySQL Shell: Built-In Help

Tweet

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.

MySQL Shell is a client that allows you to execute queries and manage MySQL through SQL commands and JavaScript and Python code. It is a second generation command-line client with additional WebOps support. If you have not installed MySQL Shell yet, then you can download it from MySQL’s community downloads, Patches & Updates in …
