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!

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.

D1_ERROR: To execute a transaction, please use the state.storage.transaction() or state.storage.transactionSync() APIs ...

and after some research, I am a bit confused about the current state of D1 vs durable objects.

In order to use transactions via state.storage.transaction(), do I need to stop using D1 and switch over to DO? Or does state.storage.transaction() somehow work for existing D1 databases as well?

ctrl-z•6/13/25, 9:13 AM

also, a related question, as of today, is D1 actually implemented via DO? Is it just the sqlite interface to DO?

lambrospetrouOP•6/13/25, 9:13 AM

That's probably an underlying error from Durable Objects that we shouldn't surface to users since you don't manage the underlying DOs and cannot run that anyway through D1.

What SQL did you try to run that gave you that error? I don't think I saw it before surfacing to users.

To summarize about transactions, since D1 is remote from your worker the traditional transaction approach of opening a transaction and interleaving JS code with SQL doesn't work (at least with the current implementation). The D1 batch query runs all the given queries within a transaction if you want multiple statements to be executed atomically.

I'm not running sql directly. I'm currently implementing an adapter for an ORM project called remult, and their test suite failed with that error https://github.com/nerdfolio/remult/blob/main/projects/tests/dbs/shared-tests/db-tests.ts#L951-L970

So sounds like the short answer still is D1 does not currently js-based transactions and sql-based transactions are done via batching.

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.

I am not sure what's the question here, though.

Regarding the slow latencies, it can be anything. Next time they happen send us the database and account IDs so that we can investigate. When the underlying datacenter has network issues certain operations take longer, so that's just one possible cause. The network can also impact just the response on its way back, not necessarily the query processing. Especially if you return MBs So, without exact timeranges we can't say what is the cause.
