Hi!

Data focused 61st DevClub.lv:
- Edgars Francis from Scope Technology will give a talk D-Insight – An Analytics Platform for Analyzing and Characterizing Driving Behavior
D-Insight is a powerful analytics platform used for Analyzing and Characterizing Driving Behavior, Driving Context, Insurance Risk, and Revenue Modeling. With powerful and flexible excel-like formulas it empowers insurance companies to analyse driver behaviour – how, where, when and under what circumstances insurance clients have driven.
D-Insight is used by Insurance Companies to create their Usage-Based Insurance (UBI) products, and the platform supports both “Pay-As-You-Drive” (PAYD) and “Pay-How-You-Drive” (PHYD) product where the insurance premiums are calculated dynamically, according to the driver behaviour.(Language — Latvian)

- Yury Nevinitsin from Odnoklassniki.ru will share an successful experience of deploying Druid in place of MSSQL
“Druid is a high-performance, column-oriented, distributed data store” http://druid.io
I will tell how they solved the situation when MSSQL-based statistics system (50TB sized) became:
– slow: average response time was many times slower than required
– unstable: at peak hours it was up to 30 minutes late
– expensive: expences for Microsoft licences could be millions USD.
In Odnoklassniki.ru Druid is used to store and query operational statistics for the last 2 years. At the moment we process tens billons records each day (hundreds gigabytes by size).
Why Druid?
We chose druid (among open-source solutions) because it promised us high-performance, scalability and fault-tolerance. All three properties were required, and there were no other solution at the moment of making decision.

Yury is a senior developer at Odnoklassniki.ru, working on statistics system back-end. In the past he was lead developer in Moi Mir@Mail.ru social network.
- Bogdan Ozerkin from SIA Dynatech will give a talk Log management in a Service architecture
When you implement service architecture, there are many ways to screw up, one of which would be to miss out on debugging solutions. As you detect problems in your services, valuable insights on what’s going on “inside” should be available, in order to be able to react on incident and provide solutions faster. In this talk, I would like to dig in to the nature of logging, providing an overview on what it is and how do it in a Service architecture. Additionally tell You a story about how we created an Ad hoc solution for our infrastructure
