lambrospetrou•6/9/25, 6:22 PM

What do you mean downtime? There shouldn't be a downtime. The replica information is cached in the locations where it has been used once, so it needs a few hours for them to completely stop being used, though.

at least once a week i feel like there are 10-20min outages

Can you give me details about this? What kind of outages? Was it due to replicas? In all regions, or specific ones? I don't recall some past message here. Feel free to DM me the database and account IDs and will check it.

Database stucks during export, can not view from Cloudflare dashboard as well. (API error 500)

dsds10•6/10/25, 8:57 PM

Afaik you have 3 ways to achieve this:

1. update worker bindings via the API to add an additional d1 database (docs states that you can theoretically bind up to 5k dbs, env limits)
2. use d1 over http (but queries are way slower)
3. use durable objects with sql storage (downside is that you can‘t use the tooling d1 offers)

I triggered the issue again.

The first time I tried to export:
"X [ERROR] cell.replace is not a function"

The second time I tried to export:

Now the database stucks, seems I need to wait until tomorrow again.

Hi, if I have two D1 databases in my account, one for production and one for staging. Is there anyway to limit access to production database to some of the account members? Say we have compliance on who can access customer's data. It seems there is no resource based permission management for members in the account. Is there a solution other than creating a separate Cloudflare account for production environment? Thanks!

Unfortunately there aren't any resource level permissions at the moment. You can restrict writing to databases but as long as they have d1:readd1:read permissions they would be able to read all DBs.

SaM•6/12/25, 6:10 AM

Hi everyone! I have a question about Cloudflare D1 replication and latency:

My D1 database’s primary region is APAC (I’m in India).

If I call my Worker API without read replicas, my responses in India are around 300ms.

If I enable read replicas, my response time in India goes up to 500–700ms.

For a user in the UK, with read replicas enabled, the response comes from the WEUR region and is under 100ms (which is great!).

But if I turn off read replicas, UK users get responses from APAC and latency is over 700ms.

My question:
Is there any way to make my responses in India faster with D1 replication enabled?
Why is enabling read replicas increasing my latency locally, and what’s the best way to optimize for both my region (India) and global users?

Any tips or best practices would be greatly appreciated!

lambrospetrou•6/12/25, 8:30 AM

Without database/account ID details I cannot know for sure, but I can see what you describe happening if the replica you are hitting from India is farther from your main database depending on which region you get routed since India doesn't have a region yet.
There is a plan for optimizing the choice of the replica to be the closest but now it's just selecting the replica of your closest region.

Do you send traffic in this database? I only see a handful of requests over the past few days.
Either way, my theory seems to be right. Your main database is in Singapore, and the replica of the same region ended up in Japan. :facesad:
Replica placement is the core priority for improving before going GA, so please continue reporting these cases and we examine them.

It would be great if you guys add a replica in India as well. India has many users but not always have fast internet. Reducing server side latency would increase user experience.

Hi cloudflare devs, I have a D1 database that I'm using for my production use-case. It is a very small db, but from day 1, I've been facing random >10s wall time on my workers on random db operations. I've optimized queries. This was okay until I was the primary user, but I'm now looking to having more tenants and convert to a 1 db/tenant architecture, so therefore reaching out for help, as I would like to keep using D1.
