This talk describes the architecture of data analytics platform service of Treasure Data, what we use Ruby/JRuby for and what we don't use Ruby for. We will discuss the many reasons, not only for productivity and performance.
Data analytics platform architecture is very far from well-known web service architecture. There are huge scale queues, workers, schedulers and distributed processing clusters, besides well-known parts like web application servers written in RoR and RDBMSs.
