Data warehousing on Hadoop - after a few months in production
Medical laboratory instruments produce immense volumes of log files. Until recently, they were used only for trouble shooting and maintenance purposes. However, hidden inside are insights that could allow the laboratory managers to streamline and optimize the diagnostic process.
The goal of the StraDa project is to gather the log files from hundreds of Roche diagnostic instruments spread around the world, transform these TBs of data into actionable information and make it available for the business users.
Yet another data warehouse? Sounds reasonably easy? Well, so we thought. And we were wrong.
Please come to learn about some of the mistakes we made and problems we encountered, so you can avoid them.
I will have slides, but I don’t need to follow them. Ask questions! Challenge me! Share you own experience!

The goal of the StraDa project is to gather the log files from hundreds of Roche diagnostic instruments spread around the world and transform these TBs of data into a data warehouse.
We built it, but it wasn't a straightforward task.
Please come to learn what was the biggest mistake we made and then come back at 19:30 for a full-blown session.
