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 can [&]

MySQL Resource Groups, introduced in MySQL 8, provide the ability to manipulate the assignment of running threads to specific resources, thereby allowing the DBA to manage application priorities. Essentially, you can assign a thread to a specific virtual CPU. In this post, Im going to take a look at how these might work in practice. [&]

There are many organizations where front/web-facing applications use MySQL and back end processing uses PostgreSQL®. Any system integration between these applications generally involves the replication—or duplication—of data from system to system.
