Observability 2.0: Beyond the Three Pillars, Embracing Wide Events

Charity Majors of Honeycomb introduced the concept of 'Observability 2.0,' representing an evolution from the traditional 'metrics, logs, and traces' paradigm. Observability 2.0 centers around 'wide events' as a single source of truth – high-cardinality, high-dimensional event data rich in context. This allows for the retroactive derivation of metrics, logs, and traces, addressing issues like data silos and limitations of pre-aggregation. However, this transition presents challenges in event generation, data transport, storage, and querying. GreptimeDB, an open-source analytical observability database, aims to overcome these hurdles. It supports OpenTelemetry, features a built-in transformation engine, high-throughput real-time ingestion, real-time query APIs, and materialized views, providing a robust infrastructure for Observability 2.0.
