I’ve worked with several customers over the past year helping them scale out their data processing using Pentaho Data Integration. These customers have some big challenges - one customer was expecting 1 billion rows / day to be processed on their ETL environment. Some of these customers were rolling their own solutions; others had very expensive proprietary solutions (Ab Initio I’m pretty sure however they couldn’t say since Ab Initio contracts are bizarre). One thing was common: they all had billions of records, a batch window that remained the same, and software costs that were out of control.

None of these customer specifics are public; they likely won’t be which is difficult for Bayon / Pentaho because sharing these top level metrics would be helpful for anyone using or evaluating PDI. Key questions when evaluating a scale out ETL tool: Does it scale with more nodes? Does it scale with more data?

I figured it was time to share some of my research, and findings on how PDI scales out and this takes the form of a whitepaper. Bayon is please to present this free whitepaper, Pentaho Data Integration : Scaling Out Large Data Volume Processing in the Cloud or on Premise. In the paper we cover a wide range of topics, including results from running transformations with up to 40 nodes and 1.8 billion rows.

Another interesting set of findings in the paper also relates to a very pragmatic approach in my research - I don’t have a spare 200k to simply buy 40 servers to run these tests. I have been using EC2 for quite a while now, and figured it was the perfect environment to see how PDI could scale on the cheapest of cheap servers ($0.10 / hour). Some other interesting metrics, relating to Cloud ETL is the top level benchmark of a utility compute cost of ETL processing of 6 USD per Billion Rows processed with zero long term infrastructure commitments.

Matt Casters, myself, and Lance Walter will also be presenting a free online webinar to go over the top level results, and have a discussion on large data volume processing in the cloud:

If you’re interested in processing lots of data with PDI, or wanting to deploy PDI to the cloud, please register for the webinar or contact me.
