Opensensors handles lots of time-series data. We need the flexibility of ad-hoc queries and analysis, while still efficiently storing all the data reliably. This talk outlines a solution, using Elasticsearch and Cassandra in tandem to achieve the goals.
The talk will go over some of the problems that we faced and that drove us to this architecture, and how Clojure enabled us to rapidly change and evaluate different approaches.

Martin has been doing Clojure full time for 4 years in various projects ranging from finance, property websites and IOT startups. Currently he is head of engineering at Opensensors.io building solutions with a Clojure backend and frontend stack. He is very interested in programming languages and is always trying to learn new (and old!) ones.
