Version
All versions.

Similarly to https://github.com/apollographql/apollo-android/issues/2505, I guess we need a clearAllAndPublish?

[piotr-pawlowski]

Yes, it seems to be the best solution.

any updates here ?
seems like still apolloStore.clearAll() doesn't trigger publish and observers don't show empty results

@Hospes At the moment clearAll() still doesn't publish to observers, so you'll need to handle that with your own mechanism. I've added this issue to the backlog of issues we want to tackle as part a cache improvement effort.

Hi @BoD is there any updates on this ? 👀

[BoD]

Hey @jszmltr thanks for the ping! The issue is still there, but I'll have a look to at least determine what would be needed to have this fixed. In the meantime manually calling ApolloStore.publish with a select set of keys is probably your best bet.

With #6337 you can call publish() with a special key set ApolloStore.ALL_KEYS after your call to clearAll(). This will notify all watchers. This will be in the next release, in the meantime it can be tried out with the snapshots.
