%description
ClickHouse manages extremely large volumes of data in a stable and sustainable
manner. It currently powers Yandex.Metrica, world’s second largest web
analytics platform, with over 20.3 trillion database records and over 20
billion events a day, generating customized reports on-the-fly, directly
from non-aggregated data. This system was successfully implemented at CERN’s
LHCb experiment to store and process metadata on 10bn events with over 1000
attributes per event registered in 2011.
