In this two part series, I’m going to explain explain. No, the repetition is not a pun or a typo. I’m talking about explain(), the most useful MongoDB feature to investigate a query. Here, I’ll introduce the index types available in MongoDB, their properties and how to create and use them. In the next article […]Read more
One of the common ways to classify database workloads is whether it is “read intensive” or “write intensive”. In other words, whether the workload is dominated by reads or writes.
Why should you care? Because recognizing if the workload is read intensive or write intensive will impact your hardware choices, database configuration as well as […]
For optimum performance, a PostgreSQL database depends on the operating system parameters being defined correctly. Poorly configured OS kernel parameters can cause degradation in database server performance. Therefore, it is imperative that these parameters are configured according to the database server and its workload. In this post, we will discuss some important kernel parameters that […]Read more
Percona Monitoring and Management (PMM) provides an excellent solution for system monitoring. Sometimes, though, you’ll have the need for a metric that’s not present in the list of node_exporter metrics out of the box. In this post, we introduce a simple method and show how to extend the list of available metrics without modifying the […]Read more

If you are using large EBS GP2 volumes for MySQL (i.e. 10TB+) on AWS EC2, you can increase performance and save a significant amount of money by moving to local SSD (NVMe) instance storage. Interested? Then read on for a more detailed examination of how to achieve cost-benefits and increase performance from this implementation.
