They work together through bindings and APIs, but they are separate products with different data models—not one interchangeable database.
How Workers and the data platform fit together
A Worker handles application logic, such as responding to a request, serving frontend assets, or calling an API. From that code, bindings provide access to Cloudflare services suited to particular jobs. Cloudflare describes Workers as running frontend and backend logic at the edge; this is product positioning, not an independent performance benchmark. See Cloudflare Workers and its runtime documentation.
Think of Workers as the application layer and the data services as capabilities it can call. For a typical web application, a Worker can handle routes and frontend delivery, D1 can store structured application records, and R2 can hold uploaded files. A collaboration feature might add Durable Objects to coordinate live state and WebSockets, while Queues move slower work into background processing. Cloudflare’s web application use cases describes these kinds of patterns.
Which Cloudflare data service fits your workload?
Choose according to the shape of the data, how it is accessed, and whether the application needs consistency or coordinated state. Cloudflare’s storage and data product selection guide, last updated October 1, 2026, distinguishes these roles:
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
| Need | Service | Fit and boundary |
|---|---|---|
| Structured application data queried with SQL | D1 | Managed serverless SQL positioned for read-heavy application data. |
| Uploads, assets, or large unstructured files | R2 | Object storage with an S3-compatible interface. |
| Frequently read, relatively stable key-value data | Workers KV | Globally cached key-value storage; updates are eventually consistent. |
| State that needs coordination, such as a shared session or live collaboration room | Durable Objects | Globally unique, stateful instances with transactional storage; design around the per-instance coordination model. |
| Deferred jobs, batching, or service-to-service messages | Queues | Background messaging integrated with Workers. |
| An existing Postgres or MySQL database | Hyperdrive | Connects Workers to the existing database, with pooling and caching capabilities. |
| Custom time-series metrics and usage analytics | Analytics Engine | Write and query metrics from Workers. |
| Embeddings and vector search | Vectorize | Vector database for semantic search and related AI patterns. |
| Streaming ingestion into object storage | Basin Pipelines | The guide describes streaming ingestion and batching to object storage; verify current maturity and availability before relying on it. |
How to choose between the services
- Start with the data model. Use SQL for relational records, object storage for files, or key-value storage for simple lookups.
- Check consistency and coordination needs. KV is eventually consistent; where coordinated, transactional state is needed, Durable Objects are a different fit.
- Decide whether to keep an existing database. Hyperdrive is for connecting Workers to an existing Postgres or MySQL database rather than replacing it with a new Cloudflare database.
- Separate request work from background work. Queues let a Worker hand off deferred tasks instead of doing every job in the request path.
- Consider operational requirements. Evaluate access patterns and the capabilities the application needs; the products are not universal substitutes for one another.
What Workers’ global runtime does—and does not—tell you
Cloudflare documents Workers as using a V8-based runtime across its global network. That describes the execution model, but it does not prove that every application will be faster or cheaper. Performance and cost depend on the particular workload, architecture, and service choices; the cited product documentation does not establish a universal comparative benchmark or cost advantage.

For uploads and other object data, R2 offers an S3-compatible interface. Cloudflare’s R2 architecture documentation, last updated April 21, 2026, describes R2 as having no egress fees. Treat that as Cloudflare’s service description and check its current terms when planning a deployment.
