Open Houseで発表されたオブザーバビリティ関連の新機能：MCPサーバー、AI Notebooks、ClickStack Cloud

The Open House event brought together the ClickHouse community for three days of workshops, technical sessions, product announcements, and discussions on the future of real-time data. Key highlights included the unveiling of ClickStack Cloud, a fully managed serverless observability platform built on ClickHouse, which simplifies infrastructure management for users by allowing them to send OpenTelemetry data to managed endpoints and explore logs, metrics, and traces via ClickStack UI. Additionally, the Managed ClickStack, designed for teams seeking operational control over their observability stack, was announced for general availability. AI Notebooks entered beta, providing a persistent investigation workspace that helps engineers document, share, and explore alternative hypotheses without losing context. A new ClickStack MCP server was also introduced, enabling integration with external AI systems and agents, offering structured tools for observability workflows that go beyond basic SQL interfaces. These initiatives reflect a broader trend towards more collaborative and programmable observability systems, reducing operational overhead while enhancing investigative capabilities.
