ClickHouse Cloud Dashboards: Unlocking Data Insights
Introduction
ClickHouse Cloud Dashboards are now Generally Available, representing a significant leap in data visualization capabilities within the ClickHouse ecosystem. Originally launched in beta last December, this feature allows users to create interactive visual dashboards, collect insightful data, and share visualizations derived from saved queries. As we reflect on the past six months since our launch, we've gathered invaluable user feedback and carefully analyzed feature adoption trends to enhance and expand this tool. In this blog post, we'll explore how we've utilized our own dashboards feature to monitor the adoption of these capabilities and share our strategic vision for the future of ClickHouse Cloud Dashboards.
The Problem We Solved
ClickHouse is an extraordinary database tailored for analytics, and ClickHouse Cloud is the premier platform for deploying it effectively. Historically, while the ClickHouse Cloud console has included a SQL console for several years, it had a notable limitation: users were required to write and execute SQL queries to retrieve their data. This posed a significant obstacle to broader adoption within various organizational roles. Internally, we rely on ClickHouse Cloud as our primary data warehouse, yet many team members, particularly those in non-technical roles, were hesitant to engage with SQL, preferring simpler, dashboard-based access to data insights.
To address this challenge, we integrated Superset on top of our ClickHouse Cloud service and developed dashboards tailored for comprehensive team engagement. The core issues became evident: a large portion of users lack confidence in writing SQL and anticipate an intuitive, dashboard-based approach to data access. Moreover, our original SQL console setup did not facilitate the comparison of results from multiple queries side-by-side, which was imperative for effective analytics.
With the introduction of dashboards, our goal is to empower users at all levels to interact with the data effortlessly. Dashboards act as visual representations of SELECT queries, a principle that forms the backbone of our new feature. Users can create dashboards simply by selecting data from a table and saving their queries, enabling an intuitive way to visualize data.
How Dashboards Work
At their core, dashboards are designed for ease of use. Users can select saved queries or craft new ones to create visualizations that best represent their data needs. Each dashboard utilizes Vizhouse, our powerful charting library that underlines all ClickHouse Cloud frontend applications. This library supports various visualization types, including tables, bar charts, line charts, pie charts, and beyond, effectively catering to diverse analytic needs.
To enhance usability, we've incorporated auxiliary elements like spacer bars and text boxes, enabling users to organize and annotate their dashboards efficiently. Dashboards can also be made interactive using ClickHouse Query Parameters, which allow users to dynamically alter the displayed data based on their preferences. Responding to robust user demand, we've implemented three different permission levels that enable dashboard creators to share their work with individuals who may only have view-only access.
We strategically prioritized detailed telemetry upon launch to comprehend user behaviors regarding the dashboards. By leveraging two tables in ClickHouse, we effectively captured metrics such as clicks, query executions, dashboard creations, and visualizations generated. For instance, we maintain a dedicated analytics table—forensics_v2—that records a wealth of operational data, allowing us to track feature adoption and engagement easily. Our analytic queries operate with impressive speed, verifying the power and efficiency of ClickHouse in real-time analytics.
Conclusion
In conclusion, the launch of ClickHouse Cloud Dashboards embodies our commitment to democratizing data access and enhancing usability for all users, regardless of their technical prowess. By shifting the paradigm from SQL query dependency to intuitive visual dashboards, we are not only facilitating data-driven decision-making but also fostering a culture of self-service analytics within organizations. As we proceed into the future, our roadmap highlights key enhancements focused on enriching the dashboard experience, embracing AI capabilities, and developing functionalities that allow for easier embedding and sharing of dashboards. We encourage you to witness firsthand how ClickHouse can transform your data into impactful insights.
