The Value of Database Support
+0 Vote Up -0Vote Down

In this post, I’ll discuss how database support is good for your enterprise.

Years ago when I worked for the MySQL Support organization at the original MySQL AB, we spoke about MySQL Support as insurance and focused on a value proposition similar to that of car insurance. You must purchase car insurance before the incident happens, or insurance won’t cover the damage. In fact, most places around the world require automobile insurance. Similarly, many organizations that leverage production-use technology have their …

MongoDB Administration Checklist for MySQL DBAs
+0 Vote Up -0Vote Down

In this blog, I discuss a MongoDB administration checklist designed to help MySQL DBAs.

If you are MySQL DBA, starting MongoDB administration is not always an easy transition. Although most of the concepts and even implementation are similar, the commands are different. The following table outlines the typical MySQL concepts and DBA tasks (on the left) to corresponding MongoDB ones (on the right). If you happen to be a MongoDB DBA and want to learn MySQL administration, you can use the same table looking from right to left.

I’ve also created a webinar, …

I have been collecting results for MongoDB and MySQL to understand storage engine performance and efficiency. I use them for single-threaded workloads to learn when storage engines sacrifice too much performance at low concurrency to make things better at high concurrency.

TRIM, iostat and Linux
+0 Vote Up -0Vote Down

I use iostat and vmstat to measure how much CPU and storage is used during my performance tests. Many of the database engines have their own counters to report disk IO but it is good to use the same measurement across engines. I use the "-k" option with iostat so it reports KB written per second per device.

The rate of writes to storage can be overstated by a factor of two in one case and I don't think this is widely known. When TRIM is done for an SSD then the Linux kernels that I use report that as bytes written. If I create an 8G file then I will see at least 8G of writes …
