Hi @pmontepagano-dialpad, thanks for raising this feature request! I understand the inconvenience of not being able to persist data across emulator restarts. We are aware of this request and do have it in our backlog already. In the meantime, I can point you to import/export for Datastore Mode, that might serve as a workaround for your data persistence problem in the short term: https://cloud.google.com/datastore/docs/emulator#import_entities_into_the_emulator. Please let me know if this is suitable work around for you. If not, I can make some notes as part of the persistence work and push that along.
Note: Persistence is a feature across all of the Firestore Emulator and I believe import/export is how existing Firestore Native customers work around this problem today: https://github.com/firebase/firebase-tools/issues/2269
We've recently migrated our database from Datastore to "Firestore in Datastore mode". We now want to stop using the Datastore emulator in our tests and local development environments and instead replace it with the Firestore emulator. In other words, we want to replace
gcloud beta emulators datastore start
withgcloud emulators firestore start --database-mode=datastore-mode
.But unlike Datastore emulator, the Firestore emulator does not persist data. The documentation states:
This is an inconvenience for local development environments, where engineers expect state to be persisted across restarts. I would like to request a new flag to the Firestore emulator (at least in Datastore mode) to be able to persist state across restarts (and indicate a path where persistence data should be stored).
