It has been over 2 months since the first satRday conference ended and I shared some quick impressions on that, where I also promised a follow-up post on my experiences as ending up being the main organizer of the event – this is what you are reading now. Although the idea was born at the EARL Boston conference last year, and I decided to take part in the project while living in Los Angeles – the conference took place in Budapest after all as logistics seemed to be easier there thanks to my closer relationship to the Hungarian R User Group.

One of the best things I like in working at CARD.com is that I am not only crunching R code in 24/7, but I also have the chance to interact with and improve the related data infrastructure with some interesting technologies. After joining the company in January, I soon realized that while Impala is a very powerful database for handling data that do not comfortably fit in MySQL, it’s still not as fast as one might expect when querying large amount of data from R. Sometimes I had to wait several minutes for a query to run! So I used this spare time to think about how to improve the workflow.
