AUTOINCREMENT literally just prevents reuse of row IDs from deleted rows, so if you're fine reusing row IDs then just don't specify it.

hi guys, will there be a feature which allows foreign key check to be turned off while migrating database? I have an issue here: https://github.com/cloudflare/workers-sdk/issues/5438

Tony Leung•3/31/24, 3:52 PM

In my experience, having AUTOINCREMENT in database will make a huge performance impact on database cluster. Everytime I insert a new record, the database has to lock up the table and generate new ID for that record. I have to let it check across cluster or turn off cross-cluster check, which might cause an conflict. So unless that table don't have much activity and records are inserted in batches or you are not clustering/replicating the database, having a AUTOINCREMENT column in database is not a good idea. Use UUID or having a key generation service is better. I personally use ULID to allow time-based sorting on my database without indexing the created_atcreated_at column since most of tables are required to be sorted with created_atcreated_at descending.

Thank you for your response.

Unfortunately, last_insert_rowid is not thread safe and should be used only in the same transaction. (Its local to the connection actually, but if the connection drops, you're left with tangling rows).
Having a temporary table is equivalent to having the same table with a flag (is_orphan) I think.

As for the guid, you're in the mercy of collisions, maybe equivalent to having a monotonically incremented separate table (sequence).

Unfortunately, it is indeed a 2-phase-commit problem, no solution feels right. Which is why posted the question on how people are handling it.

It is very unfortunate that D1 forces these problems on the consumer and that there is no clear guidance. Is it that much of a corner case wanting to insert an "order" with "order-lines" in a transactional manner?

Jason Hostetter•3/31/24, 5:07 PM

Aren’t batch inserts on D1 done in the same transaction? So you could use last_row_id safely? Generating your own uid seems like a good approach, are collisions a realistic problem for your application?

John_rand•3/31/24, 5:15 PM

Both correct. Needs very carefully crafted code on the client though. Not sure how I could do that with drizzle (call the function once, store it in a variable, have subsequent batches use that var)

On the collisions, it would affect my case yes, or at least it would help me sleep better at nights. ULID could be much easier option to adopt maybe - and drizzle friendly.

Max (@rozenmd)•4/1/24, 1:16 PM

(my canned reply to this is):

D1 is built to work to the strengths of Cloudflare's network, so we can't offer extremely large databases while also loading them quickly. It's significantly easier for us to offer millions of DBs with a size limit instead.

D1 will require a change in how you think about your project's data if you're looking to build a big platform. Instead of storing all of your data in a single DB, you would store each customer's data in their own DB (and we're building tooling to make it easier to dynamically access multiple DBs in a single Worker without redeploying)

Adi•4/1/24, 1:22 PM

Just a question about future tooling you're building. Are there any plans to build an automatic sharding solution? Or something where we can add a pool of DBs and automatically write / query data from that pool?
I know this kind of opposite to the way you're encouraging us to think about these DBs, but perhaps sharding could be useful still in some cases?

Congrats on the GA! Question on smart placement and d1, is this section of the docs still up to date?

Workers with a D1 binding will always be placed in a data center near the location of the D1 database they are bound to. Subrequests to other back-end services are ignored by Smart Placement in this case.

https://developers.cloudflare.com/workers/configuration/smart-placement/#d1

The blog post briefly mentions smart placement, but from what I gather till the session and read replication APIs are in it is still the case that workers with d1 bindings only live in one location?

Great! I'd love to add d1 to an app but I was a little hesitant reading the comment that it would push all the deployments to one geo region

As I'd only use d1 in some parts/endpoints, I'd love for the others to be servable from any edge location. Could you maybe comment on if that's possible with service bindings today? There's some conflicting info on the docs last I checked: d1-database
