Fortunately the HammerDB TPC-C/OLTP workload intentionally has a great deal of contention between threads and is therefore ideal for testing spin-locks. So to test I took a system with Skylake CPUs and all storage on a P4800X SSD. In the recent MySQL 8.0.16 model name : Intel(R) Xeon(R) Platinum 8180 CPU @ 2.50GHz. linux-glibc2.12-x86_64/data

HammerDB is open source and all of the source code is available at the sourceforge Git development site here [link] or the github mirror here [link]. In fact all of this source code is also included in readable form with each and every release. Otherwise the code is the same on all platforms. Programming Languages.

From the previous post we now have source and binary copies of HammerDB for modification and test. Copying the modified source to the binary directories enables testing. After modifying the graphical options we can then update and test the TPC-C schema build and tests in mariadb/mariaoltp.tcl. and timed test.

That is, a team can work in such a way that it is less likely to cause problems for itself, by e.g., writing unit tests, having continuous integration, developing to finely grained statements of business functionality, embedding QA in the development team, and so forth. Doing these isn’t the same as increasing the probability of success.

And so it’s important to continually invest in stability, in strong infrastructure, in stable code, so that we have that strong platform to stand on as the next thing happens. Nick Finck and Steve Champeon first coined the term “progressive enhancement” in 2003. Seriously, this stuff is pure gold especially today. That was 2008.
