#Opt out of data cache reads and fast origin transfer in new pricing plan
primal shadowBOT
To opt out of Data Cache reads in your Next.js application, you can disable fetch caching. Here is how you can do it:
Disabling Vercel Data Cache
You can disable the Vercel Data Cache by using the following configuration in your Next.js application:
export const fetchCache = 'force-no-store';
Alternatively, you can opt out individual fetch requests by using the cache option:
const res = await fetch('<https://example.com',> { cache: 'no-store' });
For more details, you can refer to the Managing Vercel Data Cache (https://vercel.com/docs/infrastructure/data-cache/manage-data-cache#managing-vercel-data-cache) documentation.
Optimizing Fast Origin Transfer
To optimize Fast Origin Transfer (FOT), you can implement caching strategies for your Vercel Function responses. By caching the response, future requests will be served from the Edge Network cache, reducing FOT costs and improving performance. However, if you want to minimize FOT usage, you should ensure that your static content is served directly from the Edge Network without invoking functions unnecessarily.
For more information on optimizing Fast Origin Transfer, you can refer to the Optimizing Fast Origin Transfer (https://vercel.com/docs/pricing/networking#optimizing-fast-origin-transfer) documentation.
If you need further assistance or have specific requirements, you might want to check the Vercel Pricing Documentation (https://vercel.com/docs/pricing) for more details on managing and optimizing your usage.

@primal shadow where do I implement this exactly.? do i implement this in any fetch calls on my site? On a high level, do I do this whenever we are talking about fetched data content?
primal shadowBOT
Let me check the knowledge base for you. One moment! :books:
To opt out of data cache reads in your Next.js application, you need to implement the configuration in your fetch calls. This can be done at the individual fetch request level or globally for all fetch requests in a route segment.
Implementing at the Fetch Call Level
If you want to disable caching for specific fetch requests, you can use the cache option in your fetch calls. Here is an example:
const res = await fetch('<https://example.com',> { cache: 'no-store' });
This will ensure that the specific fetch request does not use the cache.
Implementing Globally for a Route Segment
If you want to disable caching for all fetch requests in a particular route segment, you can use the fetchCache configuration in your layout.js or page.js file:
export const fetchCache = 'force-no-store';
This will apply the no-cache policy to all fetch requests within that route segment.
High-Level Implementation
On a high level, you should implement these configurations whenever you are dealing with fetched data content that you do not want to be cached. This is particularly useful for data that changes frequently or for content that must always be fetched fresh from the server.
Example in a Next.js Page Component
Here is an example of how you might implement this in a Next.js page component:
// app/page.tsx
export const fetchCache = 'force-no-store';
export default async function Page() {
const res = await fetch('<https://api.example.com/data',> { cache: 'no-store' });
const data = await res.json();
return (
<main>
<h1>Data</h1>
<pre>{JSON.stringify(data, null, 2)}</pre>
</main>
);
}
In this example, the fetchCache configuration is set to force-no-store at the route segment level, and the individual fetch request also specifies cache: 'no-store'.
For more details, you can refer to the Next.js documentation on data fetching, caching, and revalidating (https://nextjs.org/docs/app/building-your-application/data-fetching/fetching-caching-and-revalidating).

@primal shadow what about opting out of fast origin transfer. what is that even?
primal shadowBOT
Let me check the knowledge base for you. One moment! :books:
Understanding and Opting Out of Fast Origin Transfer
Fast Origin Transfer (FOT) represents the data transferred between Vercel's Edge Network and Vercel Compute. This typically involves data that is fetched from your serverless functions or other backend services and then delivered to the Edge Network for distribution to end users.
What is Fast Origin Transfer?
Fast Origin Transfer occurs when:
- Data is transferred from Vercel Compute (e.g., serverless functions) to Vercel's Edge Network.
- This data is then cached and served to end users from the Edge Network.
Optimizing or Minimizing Fast Origin Transfer
To minimize Fast Origin Transfer, you can implement caching strategies to reduce the need for repeated data transfers between Vercel Compute and the Edge Network. Here are some strategies:
-
Implement Caching for Serverless Functions:
By caching the responses of your serverless functions, you can reduce the number of times these functions need to be invoked, thereby reducing FOT.// Example of caching a serverless function response export default async function handler(req, res) { const data = await fetchDataFromDatabase(); res.setHeader('Cache-Control', 's-maxage=86400, stale-while-revalidate'); res.status(200).json(data); } -
Use Static Site Generation (SSG):
For mostly static sites, you can use Next.js's Static Site Generation to pre-render pages at build time. This reduces the need for serverless function invocations and thus minimizes FOT.// Example of Static Site Generation export async function getStaticProps() { const data = await fetchDataFromDatabase(); return { props: { data, }, }; }
export default function Page({ data }) {
return (
<main>
<h1>Data</h1>
<pre>{JSON.stringify(data, null, 2)}</pre>
</main>
);
}
3. **Use Incremental Static Regeneration (ISR):**
ISR allows you to update static content after the site has been built, without needing to rebuild the entire site. This can help in reducing FOT by serving static content whenever possible.
```javascript
// Example of Incremental Static Regeneration
export async function getStaticProps() {
const data = await fetchDataFromDatabase();
return {
props: {
data,
},
revalidate: 60, // Revalidate at most once every 60 seconds
};
}
export default function Page({ data }) {
return (
<main>
<h1>Data</h1>
<pre>{JSON.stringify(data, null, 2)}</pre>
</main>
);
}
Additional Resources
For more detailed information on optimizing Fast Origin Transfer, you can refer to the following documentation:
- Optimizing Fast Origin Transfer (https://vercel.com/docs/pricing/networking#optimizing-fast-origin-transfer)
- Vercel Pricing Documentation (https://vercel.com/docs/pricing)
By implementing these strategies, you can effectively minimize Fast Origin Transfer and optimize your usage and costs on Vercel. If you have further questions or need more specific guidance, feel free to ask!

@primal shadow if i opt out of data cache, is there an adverse effect and could i potentially incur other costs with vercel?
primal shadowBOT
Let me check the knowledge base for you. One moment! :books:
Opting out of the Vercel Data Cache can have several implications, both in terms of performance and potential costs. Here are some key points to consider:
Potential Adverse Effects
-
Increased Latency:
- Without caching, every data fetch will result in a network request to the origin server. This can increase the latency for your users, as data will not be served from a nearby cache.
-
Higher Load on Origin Server:
- Your origin server will need to handle more requests, which could lead to higher server load and potentially slower response times if the server is not adequately scaled.
-
Temporary Increase in Request Times:
- If you purge the Data Cache, there will be a temporary increase in request times as new data needs to be refetched and cached again.
Potential Costs
-
Increased Bandwidth Costs:
- More frequent data fetches from the origin server can lead to higher bandwidth usage, which might incur additional costs depending on your hosting provider's pricing model.
-
Higher Compute Costs:
- If your application relies on serverless functions or other compute resources to fetch data, opting out of caching can lead to more frequent invocations of these functions, potentially increasing your compute costs.
Managing and Reviewing Usage
To manage and review your usage, you can follow these steps:
-
Reviewing Your Usage:
- Navigate to your Vercel dashboard (https://vercel.com/dashboard/usage) and go to the Usage tab. Under Data Cache, you can see the total usage for your team or account, including bandwidth, revalidations, and requests.
-
Purging Data Cache:
- If you need to delete all cached data and force revalidation, you can purge the Data Cache. This can be done under your project's Settings tab in the Data Cache section.
Example of Disabling Data Cache
Here is how you can disable the Vercel Data Cache in your Next.js application:
// Disable caching globally for a route segment
export const fetchCache = 'force-no-store';
// Disable caching for an individual fetch request
const res = await fetch('<https://example.com',> { cache: 'no-store' });
For more details, you can refer to the Managing Vercel Data Cache (https://vercel.com/docs/infrastructure/data-cache/manage-data-cache#managing-vercel-data-cache) documentation.
Conclusion
While opting out of the Vercel Data Cache can provide more control over data freshness, it is important to weigh the potential performance impacts and additional costs. Monitoring your usage and understanding your application's requirements will help you make an informed decision.
