I know that on the backend, once a DO is created, it isn't ever garbage collected. As in, if I create a stub to the same DO ID, it will spawn in the same place, even days/weeks later, even if it doesn't have any storage attached. I'm not sure if that applies to the API too

Docs say this only applies to KV-backed DOs

boop•5/14/25, 4:38 PM

For Durable Objects with a key-value storage backend, an in-progress deleteAll() operation can fail, which may leave a subset of data undeleted. Durable Objects with a SQLite storage backend do not have a partial deleteAll() issue because deleteAll() operations are atomic (all or nothing).

I'm using the SQLite storage backend with hardly anything stored. weird deleteAll() behavior

workerBee•5/14/25, 4:55 PM

^^ I'm doing this too. The only thing I can think of is that there's a stub/reference to the particular DO instance in a worker which is preventing garbage collection. The docs describe how to create disposable DO's using alarms, but in practice it behaves quite different.

mon•5/16/25, 12:19 AM

I'd like a sanity check - I introduced a DO in a worker to test some things, but would like to rollback to the code before it was introduced. I can't do so, the error is:

'Invalid deployment: The version "[snipped]" cannot be deployed because it has a resource that was modified: the version depends on Durable Object migration "v0.0.2", but the current deployment is using migration "v0.0.3" - check the request details and try again.'

'Invalid deployment: The version "[snipped]" cannot be deployed because it has a resource that was modified: the version depends on Durable Object migration "v0.0.2", but the current deployment is using migration "v0.0.3" - check the request details and try again.'

Is it impossible to rollback, or did I miss something? I'm happy to unceremoniously kill all the DOs based on my test code

mon•5/16/25, 12:33 AM

I've bodged around it for now - I checked out the old version I wanted to deploy, modified its wrangler.toml to add a deleted_classesdeleted_classes migration in v0.0.2v0.0.2 and deployed.
It feels hacky and I'm wondering if that's the correct way to rollback after you add a DO to a worker.

Are they geographically spread out? At that usage, it might be a good idea to contact Support/your CSM if you have one, just to scope out what is possible

Tero•5/16/25, 10:34 AM

Are there any plans to add "management capabilities" for durable object instances? For example listing instances or removing storage to destroy etc? I don't want to include such temporary/one time logic in my production app, and that pretty much leaves as the only option to build a second "management app" to execute these lifecycle actions (unless I am missing something)?

plgingras88•5/20/25, 11:58 AM

Sqlite storage in DO is something very new, it barely ended its beta phasis few weeks ago. Drizzle adopted it fairly quickly, only few weeks ago the typing for DO sqlite wasn't even supported with the orm and now it is, so I feel they are working as fast as they can to adapt accordingly. Give them a little bit of time, DO's a special creature that needs the libs to work a little differently. I wouldn't be surprised your problem may be addressed in a forseable future with user adoption and bug reports.

I use drizzle purely to generate migrations for DO. Then I reuse the drizzle schema at runtime for type checking post-query responses. All actual DO request logic is pure SQL. Has worked pretty well for nearly a year now.
