Open Source cost-efficiency in action: analyzing 500B rows on a single ClickHouse server
by Alexander Zaitsev, Altinity CTO
Modern analytical databases scale very well with data size. However, when business scales with the data, infrastructure costs should be very well controlled. Cost-efficiency and performance become critical for big data analytics in many businesses.
ClickHouse is known for its speed. Speed drives cost-efficiency. In this talk I will demonstrate ClickHouse cost-efficiency by storing 500 billion (!) rows and analyzing them quickly with a single ClickHouse server. Usually you would need a beefy multi-node cluster, but the right technology and technique enable us to use far less. To prove the point I’ll show how you can store the data on a cheap Intel NUC mini PC and still obtain decent query performance. We’ll explain the magic that allows ClickHouse to do this and also discuss performance implications for more capable environments.
