What each one is

The product in its own terms, so the numbers below have context.

ClickHouse

Leader

An open-source columnar database system designed to handle large-scale analytical workloads with extremely low latency. Excels at real-time analytics, observability (logs, metrics, traces), data warehousing, and AI/ML applications.

Independently observed

GreptimeDB

A time-series and observability database that consolidates multiple signal types—metrics, logs, traces, and events—into a single queryable system using standard protocols like OpenTelemetry and Prometheus. It uses columnar storage on object storage for cost-effective scalability and provides both open-source and fully-managed cloud deployment options.
