Summary
AI Gateway Revolutionises AI Log Storage Amid Rapid Growth
In response to an ever-evolving artificial intelligence landscape, AI Gateway has emerged as a pivotal solution for managing AI inference requests. Launched in September 2023, the platform initially faced a critical challenge: extending its log storage capacity from a restrictive 30 minutes to a capability that supports indefinite storage of billions of logs. This undertaking was crucial for developers aiming to glean long-term insights from their data.

A Surge in Demand
The rapid expansion of artificial intelligence technologies has necessitated more sophisticated platforms to manage the increased volume and complexity of data. AI Gateway, capitalising on this trend, quickly became indispensable within its first year, processing over 2 billion requests. However, its initial architecture only supported a brief 30-minute log retention, posing a significant hurdle for developers who require extensive data analysis.
AI Gateway’s initial framework was built on Cloudflare Workers, leveraging the serverless platform to execute JavaScript functions across a global network of data centres. This setup, while efficient for short-term tasks, struggled under the weight of escalating data volumes. The D1 database, initially responsible for storing both metadata and actual request bodies, soon reached its limits, accommodating logs for just half an hour.
Innovating for Scale
Recognising the need for a more robust solution, AI Gateway embarked on a series of strategic enhancements. The first of these was an optimisation of the database schema, which temporarily extended log retention to one hour. While this offered a short-term reprieve, it was clear that a more permanent fix was necessary. Transitioning request bodies to R2 storage significantly eased the burden on the D1 database, pushing retention capabilities to 24 hours and providing crucial breathing room for further innovation.
As demand for historical data continued to surge, AI Gateway explored the potential of Durable Objects with SQLite. This approach initially involved sharding logs by account ID, but a 10-million-log cap per Durable Object soon necessitated a more flexible strategy. By introducing sharding by both account ID and gateway name, AI Gateway increased its capacity to a staggering 100 million logs per account. “We knew we had to think bigger to meet the needs of our users,” commented Thomas Lang, Chief Technology Officer at AI Gateway.
Complex Management Challenges
The exponential growth of AI Gateway introduced new complexities in managing thousands of unique Durable Objects. To address this, an Account Manager—another Durable Object—was deployed. This manager plays a critical role in ensuring users adhere to storage limits and maintaining system integrity, streamlining the management process and ensuring fair usage across the board.
Charting the Path Forward
Looking ahead, AI Gateway is poised to further expand its log storage capabilities. Plans are underway to implement sharded Durable Objects, a move that promises to accommodate even larger volumes of data. This evolution will provide developers with richer datasets for evaluating large language models (LLMs) and refining their AI solutions.
Detailed Analysis
The evolution of AI Gateway’s log storage highlights broader trends in data management within the AI industry. As artificial intelligence continues to permeate various sectors, the ability to efficiently store and analyse large datasets is increasingly paramount. Organisations are under mounting pressure to not only process but also derive actionable insights from vast amounts of data, necessitating innovative solutions like those developed by AI Gateway.
AI Gateway’s success in overcoming initial technical hurdles reflects a wider industry push towards decentralised and scalable data solutions. By leveraging Cloudflare’s global network and adopting advanced technologies such as Durable Objects, AI Gateway showcases how strategic planning and innovation can transform data management capabilities.
Further Development
The future of AI Gateway is closely tied to ongoing advancements in AI and data storage technologies. As the platform continues to scale, further developments in sharded Durable Objects are expected to provide even greater flexibility and capacity. These enhancements will enable developers to harness comprehensive datasets, driving more sophisticated AI model evaluations and optimisations.
Stay tuned for more updates on AI Gateway’s journey as it navigates the challenges and opportunities of the rapidly evolving AI landscape, ensuring that developers have the tools they need to succeed in an increasingly data-driven world.
