I have attended my first ever Strata + Hadoop conference a week ago in Barcelona. Strata is probably the biggest and most important applied data science conference in the commercial world. My first impression is that it is a quite big conference, with an annoyingly large number of parallel tracks (up to 8). This means that you always find yourself deciding what talk to go next, and this can be a very complex decision because some of the talks (and tracks) are extremely related. This blogpost will summarise the feelings I had after the conference and the main “buzzwords” and most mentioned tools.
