In this blog post, we’ll compare the performance of pattern matching queries vs. full-text indexes. In my previous blog post, I looked for a solution on how we can search only a part of the email address and how can we make faster queries where the condition is email LIKE ‘%n.pierre%’. I showed two possible […]

In this blog post, we’ll show that you can plot MySQL data in real time using Percona Monitoring and Management (PMM). In my previous blog post, I showed how we could load into any metrics, benchmarks into MySQL and visualize it with PMM. But that’s not all! We can even visualize most any kind of […]

From time to time I see pattern matching queries with conditions that look like this: “where fieldname like ‘%something%’ “. MySQL cannot use indexes for these kinds of queries, which means it has to do a table scan every single time. (That’s really only half true — there are the FullText indexes. In another blog […]

In this blog post, we’ll look at how you can verify query performance using ProxySQL. In the previous blog post, I showed you how many information can you get from the “stats.stats_mysql_query_digest” table in ProxySQL. I also mentioned you could even collect and graph these metrics. I will show you this is not just theory, it […]

In this blog post, we’ll checkout Percona Monitoring and Management vs. gnuplot when it comes to creating great metrics graphs. gnuplot is great, but PMM might provide graphs that are easier to read. Percona Monitoring and Management (PMM) is our free and open-source platform for managing and monitoring MySQL®, MariaDB® and MongoDB® performance, and is […]

This blog post looks at SSL connections and how they work in MySQL 5.7. Recently I was working on an SSL implementation with MySQL 5.7, and I made some interesting discoveries. I realized I could connect to the MySQL server without specifying the SSL keys on the client side, and the connection is still secured […]

In this post, I am going to show you how you can minimize the performance impact of ProxySQL rules by using some finesse. Apply Test In my previous post, we could see the effect of the rules on ProxySQL performance. As we could also see, the “apply” option does not help with 1000 tables. Are we […]

In this blog post we are going to take a closer look at ProxySQL rules. How do they work, and how big is the performance impact of having many rules? I would like to say thank you to Renè, who was willing to answer all my questions during my tests. Overview ProxySQL is heavily based […]
