The Challenge of Data Fragmentation
Cloudflare’s global network processes an astonishing one billion events per second from over 330 cities across 120 countries. With data stored in various systems—such as Postgres databases, ClickHouse clusters, Kafka streams, and BigQuery datasets—finding clarity and making sense of this information can be extraordinarily complex. Town Lake addresses this challenge by presenting a unified SQL interface that facilitates seamless querying across various data systems while ensuring data governance and access control are maintained.
The Architecture of Town Lake
At the core of Town Lake is an advanced lakehouse architecture that integrates international data sources and modern technologies. It employs components like Apache Trino, Apache Iceberg, Cloudflare R2 object storage, and DataHub for robust metadata management. This architecture allows users to execute a single query that can join data across different platforms without requiring the physical movement of data between systems. The supporting services are tasked with vital operations such as data ingestion, transformation, access control, and detection of personally identifiable information (PII).

Governance and Data Security
One standout feature of Town Lake is its closed governance model. Datasets introduced to the platform remain inaccessible until they undergo thorough automated scanning and human review. This process employs an internal tool called Skimmer, which combines automated data classification with AI capabilities to detect sensitive information. After this initial assessment, human reviewers ensure that classifications are correct before granting access, thus promoting data security and compliance.
The Integration of AI with Skipper
Building upon Town Lake, Cloudflare developed Skipper, an AI-powered analytics agent designed to provide natural language access to enterprise data. Skipper translates user questions into validated queries that utilize metadata, schema definitions, and transformation lineage. This innovative approach allows users to engage in business intelligence, security workflows, and customer support inquiries using plain language, thereby significantly enhancing the accuracy of data queries.
Dmitry Alexeenko, Head of Enterprise Engineering at Cloudflare, underscores the pivotal role of data in every Cloudflare request. With Town Lake and Skipper, tasks that once required intricate SQL or time-consuming manual investigations can now be accomplished in mere seconds.
Performance Metrics and Results
The performance of Town Lake has been impressive. In a recent evaluation, the platform processed 91,760 billing-related queries from 324 employees, showcasing its proficiency in supporting billing analyses and other operational reporting tasks. Moreover, the platform has continued to evolve, with Cloudflare reporting that simplifying prompts for the AI agent has markedly improved accuracy. Further enhancements have been made by incorporating SQL transformation logic and data lineage into the agent’s context.
The Future of Town Lake and Skipper
Looking ahead, Cloudflare has ambitious plans to deepen the integration of Skipper with existing workflows, including chat, ticketing, and development processes. The company aims to expand its Transformer pipeline, allowing teams to define curated datasets via SQL and metadata files that will be automatically deployed, monitored, and cataloged through DataHub and Skipper. Additionally, Cloudflare envisions migrating more Town Lake workloads to R2 SQL as the platform continues to advance.
Expert Insights on Architectural Implications
Patrick Joubert, CEO of Rippletide, has highlighted the crucial architectural considerations involved in placing an internal AI agent atop a unified analytics platform. He emphasizes the need for stringent control measures since the agent interacts with voluminous operational data. Distributed deterministic checks become essential for ensuring that the agent can act without compromising the integrity of the data platform.
Cloudflare’s efforts with Town Lake and Skipper are setting new standards in how organizations access, manage, and utilize their data effectively. By creating an ecosystem that interlaces robust safeguarding measures with intelligent data access, Cloudflare is proving to be a leader in the domain of enterprise data platforms.
