Recently, I’ve been working with a customer to evaluate the different cloud solutions for MySQL. In this post I am going to focus on maintenance windows and requirements, and what the different cloud platforms offer.
Why is this important at all?
Maintenance windows are required so that the cloud provider can do the necessary updates, patches, and […]
Parallel replication has been around for a few years now but is still not that commonly used. I had a customer where the master had a very large write workload. The slave could not keep up so I recommended to use parallel slave threads. But how can I measure if it really helps and […]

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 […]
