Here’s a shot of the simple transformation, in the lovely new skin of 5.4. One day we’ll get support for using variables in filter rows, and also the variable substitution in calculator will work, and then there’ll be a lot less get variables steps anyway! And as always with performance testing there’s a lot of differences, so what works today, may not work optimally tomorrow in a different scenario! But if you’re CPU starved then it can’t hurt either. It’s unlikely your incoming data is coming in at 2M r/s so therefore changing to inline probably wont help you. My hunch is that this is nothing to do with the join per-se, but probably more closely related to the fact that there are more hops. I’m not sure if this has always been the case, but it’s true right now with PDI 5.4. So you can see the “join” approach (whether 1 variable or 5) only performs at 86% of the speed of simply using the step inline. Benchmark with getting 5 variables – both ways.Just to add to the work PDI has to do make sure the variable is converted to an Integer. Run for a number of rows that takes a good 30s+ to run so that process init time becomes neglible. Benchmark “Get variables” Step inline.a dummy) otherwise you’re not testing the step in its entirety. Note: It is important to write it somewhere (e.g. Benchmark “Generate rows” Step – to prove what speed we can source and write data.Actually lets just tell you now – It’s not. There are a lot of ways to go about this, but here are some notes on a quick bit of step benchmarkingīut Why? Well a colleague said to me “why is your get variables step inline rather than a join – a join would be faster”. So decide on a line in the sand and stop once you’ve reached it.Īs with any system performance testing PDI has its own set of challenges.

In a complex system you could tune forever. (Hence one of the reasons why a performance tester is paid more than a senior tester, and is deemed a separate skill area). This is complex stuff and takes a seriously long amount of time. Doesn’t matter what the technology is either. The one thing to remember about performance related work, is never underestimate how long it takes. Back in the past I worked as a dedicated performance tester on several OLTP systems, and recently have spent quite a lot of time working performance testing/tuning PDI (Pentaho Data Integration)
