AI Site Reliability Engineering (SRE) tools often fail due to reliance on outdated observability platforms that lack long data retention, high-cardinality data, and fast query capabilities, which are crucial for effective incident investigation and response. Traditional AI SRE systems, primarily built on legacy observability frameworks, struggle with finding root causes due to short retention periods, dropped high-cardinality dimensions, and slow query processing, which limits their functionality to merely summarizing dashboards rather than providing actionable insights. ClickHouse, with its scalable and efficient data storage and querying capabilities, offers a robust foundation for building an effective AI SRE copilot by enabling long-term data retention, maintaining high-cardinality dimensions, and supporting fast queries. This creates an environment where AI can assist in reducing mean time to understand (MTTU) by correlating events, recognizing patterns, and providing context-rich insights to human engineers who remain responsible for decision-making. By integrating ClickHouse, organizations can enhance their incident response strategies and transition from a reactive to a proactive reliability posture, thereby not only addressing incidents faster but also reducing their frequency through upstream analysis and prevention.
