Very poor presentation. You can sum it as 'Awesome but boring chaos'.
Rafal had very simple topic but it seemed that he did prepped with it on last minute.
Beside good looking slides, the only message we get that something was awesome and something was boring. When you attend technical conference you want to see technical problems and technical talk. Apparently that wasn't delivered by Rafal.
Sorry that talk was big fail.
Presentation lacked talk about main topic. Instead we got some mumbled information about last project Pawel did. That they used over 30 different tools/OS projects and the only way to scale it was, to put another shards in cluster. Everything presented in poor and boring fashion.
It didn't helped that Pawel had lots of problems with spoken english :/
