so i'm worried i'll have tons of "zombie" DO instances that should be recycled so i can reuse their IDs

(more accurately, reuse the human-readable short name that i use via `idFromName`)

if you're not using persistent storage at all, the only thing that will remain after the DO leaves memory is its location, and that's an issue we know we'll need to address

to put it another way, if you clear any relevant inmemory state after the last disconnect, what stops you from reusing it?

oh interesting — when i call that API, i get a bunch of stuff like:

```
{
      "hasStoredData": false,
      "id": "bdda1d6abcd38026abd764310cadebcc54027dfca8ea795de615b9574d94a6bd"
    },
    {
      "hasStoredData": false,
      "id": "ac1fac7483039d661f5b5d65fc3f0251b82c21a9628bc3e4c1476411bc6fe2f1"
    },
```

yeah `hasStoredData: false` there means there's nothing stored

how could you tell if they went away, aside from the geographic location?  there's no other state

i guess you're saying: 'don't worry about it"

since there's no storage and assuming nobody is connected

as long as they aren't running and don't have any persistent storage

i'd love to, is there some hook i can use for this?

not really, it'd just be a question of clearing any instance variables you were using

another question is, it's say i _do_ make use of the DO Storage API. i'd want some way to bulk-delete all those DOs, for example if i deploy a new version of the gameserver worker and i actively do not want the old state because it could have unintended consequences

oh yeah, i mean a hook to know when the last player disconects. clearing the in-memory state is easy. knowing reliably when to do it is the hard part

either delete the namespace, or walk every object from the list object api and call state.storage.deleteAll

I'm assuming you're tracking all open websockets anyway, right?

i guess just in the ondisconnect/onerror handler

i guess the only situation that wouldn't reliably be called after the last player disconnects is if the DO crashes or is killed

but in that case, state is necessarily cleared anyway

got it. is there any concept of 'versioning' for DOs? i guess just environments?
