Biography: Valentine Gogichashvili

As Zalando decided to go with Java/PostgreSQL as the core technology, Valentine, already having a lot of experience working with PostgreSQL, joined the company in the autumn of 2010 to support this impressive transition. As a technical lead of Platform/Database team he is responsible for building up, maintaining and monitoring the growing set of PostgreSQL database clusters.

PostgreSQL plays a crucial role in Zalando's infrastructure, storing everything from customer information to article data and reliably backing our real-time warehouse management systems. Starting from version 9.0 we have been using every release of PostgreSQL in production and loving it more and more with every next release.

I want to share how we deploy, configure, monitor and use PostgreSQL databases to power the fastest growing and the biggest fashion e-commerce platform in Europe.

Among the challenges, I am going to talk about are:

accessing sharded and distributed data;
managing hundreds of database changes done by hundreds of developers every week;
running our databases with minimal downtimes;
configuring, controlling and monitoring more than 100 master database instances and hundreds of replicas in several data centers.
