Containing your logical backups: mydumper in docker
+1 Vote Up -0Vote Down

+0 Vote Up -0Vote Down

I installed the MariaDB 10.1 Release Candidate. Nothing interesting happened, which from MariaDB's point of view is good. But here's how I tried to make it interesting. Some of this applies to late releases of MariaDB 10.0 as well.


My habit is to download the source to directory X and then say "cmake -DCMAKE_INSTALL_PREFIX=/X" (the same directory), then "make", then "make install". That doesn't work any more.

The purpose of this project was to measure the potential overhead of VividCortex Agent, which is used by database monitoring system. This benchmark is part of a consulting engagement with VividCortex and paid by the customer.

The assumption is that VividCortex agent uses CPU processing time, and we should see an impact on user queries when the workload is CPU-intensive (how much is to be measured). The impact on IO-bound should be small or insignificant.
