What 47 Arbolus experts think of ClickHouse

The NPS landscape is strongly positive with multiple scores of 8-10 and only isolated detractors. Renewal intent is high among users whose workloads align closely with ClickHouse's strengths, notably real-time and high-throughput analytics. Stickiness is highest in more mature implementations (more than one year in use), with pilot-phase users represented primarily in high-spend and evaluative roles. Experts consistently praise query speed and scalability, while cautioning on operational complexity, update limitations, and ecosystem maturity. The dominant feedback themes are competitive TCO, rapid time-to-insight, and storage savings. Overall Customer Sentiment: Positive
