When Database Warm Up is Not Really UP

The common wisdom with database performance management is that a “cold” database server has poor performance. Then, as it “warms up”, performance improves until finally you reach a completely warmed up state with peak database performance. In other words, that to get peak performance from MySQL you need to wait for database warm up.

This thinking comes from the point of view of database cache warmup. Indeed from the cache standpoint, you start with an empty cache and over time the cache is filled with data. Moreover the longer the database runs, the more statistics about data access patterns it has, and the better it can manage database cache contents.

Over recent years with the rise of SSDs, cache warmup has become less of an issue. High Performance NVMe Storage can do more than 1GB/sec read, meaning you can warm up a 100GB database cache in less than 2 minutes. Also, SSD IO latency tends to be quite good so you’re not …

Deploying PMM on DigitalOcean

It’s very easy to install Percona Monitoring and Management (PMM) on DigitalOcean. If you’ve never used DigitalOcean before, you will find that it is user-friendly and not very expensive. For $5/month you can easily host your PMM on it, letting you monitor your simple infrastructure or try out PMM before implementing it to monitor your production environments.

Let’s prepare the DigitalOcean instance

Log in to DigitalOcean (DO) control panel and click “Create Droplet.”

Thanks to DO you can skip the boring OS setup and save time by using the Docker “One click app” in DO and the Docker image from PMM.

Note: After clicking on “Docker…” choose an instance size that accommodates your budget – PMM can run on as little as the 1GB 1vCPU instance!

Note: Scroll again!

Next step – select a nearby region …

Plot MySQL Data in Real Time Using Percona Monitoring and Management (PMM)

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 data from MySQL in real time. I am falling in love with the MySQL plugin for Grafana — it just makes things so easy and smooth.
