Found for this topic "Percona Live":
Opensource database management systems conference Percona Live this time took place on November 5-7 in Germany, Frankfurt am Main. Over last couple years ClickHouse became a solid member of this community as demand in analytics with subsecond latencies appeared to be pretty high.
For those who haven't heard, Percona Live is probably one of the largest international conferences about opensource database management systems, having 12 talk tracks in parallel. It's been around for many years and initially it was focused mainly on MySQL (and had that in it's name), but nowadays it is more generic and other products of this category get lots of attention too. Needless to say that for a relatively new player on the market like ClickHouse, it's been a great opportunity to spread the word about the technology and how exactly it allows to perform analytics on petabytes of data in real time.
