Next we are going to build a PostgreSQL test schema using the HammerDB CLI as follows: Copy Code. So instead we are going to take a cut down version of the HammerDB TPROC-C driver script and do the same in Python and use the HammerDB infrastructure to measure performance.

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.

Also it is interesting to note that the impact of this change was not observed in other databases or other MySQL storage engines such as MyRocks the only noticeable impact with HammerDB workloads occurred in MySQL with InnoDB where in the source code ut0ut.cc Copyright (C) 2003-2018 Steve Shaw.

In particular with a workload such as HammerDB there is a lot of emphasis on locking and latching that is not seen in a sysbench workload and therefore you may see gains in modifying the InnoDB storage engine code.

I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R. I also applied Six Sigma to capacity planning and presented this at a conference in 2003. I also helped out in the run-up to the 2004 Athens Olympics.

This is mixing concerns and leads to code that becomes strongly coupled, monolithic, hard to write, hard to read, hard to evolve, hard to test, and hard to reuse. In 2003, Gregor Hohpe and Bobby Woolf released their book Enterprise Integration Patterns. Schema evolution practices were rarely in place.
