GreptimeDB

GreptimeDB is a unified observability database that ingests metrics, logs, traces, and wide events through standard protocols like OpenTelemetry and Prometheus Remote Write, storing them in columnar format on object storage. It solves the problem of managing separate systems for each signal type by enabling SQL and PromQL queries across all data, with features like streaming, materialized views, and alerting. The product targets developers, DevOps, SRE, and IT teams in mid-market and enterprise companies, particularly those in connected vehicle, IoT, and observability domains. It is positioned as an Observability 2.0 solution that reduces storage costs and complexity compared to maintaining separate systems.
