Cloud Firestore Beta结束后REST API及数据相关问题咨询

Let’s break down your questions clearly—this is a common concern when working with beta Google Cloud services, and Firestore’s transition to general availability (GA) was pretty straightforward:

1. Will the base URL change from v1beta1 to something like stable? #

Nope, Google’s API versioning follows a standard pattern where beta releases use version numbers with a beta suffix (like v1beta1), while GA versions use clean major version numbers (like v1).

For Firestore, once it exited beta, the stable base URL became https://firestore.googleapis.com/v1/—not a stable path segment. This aligns with most Google Cloud APIs, where version numbers reflect maturity rather than a generic "stable" label. You can expect future stable releases to stick to this major versioning scheme (e.g., v2 if there’s a breaking change down the line).

2. What happens to data stored during the beta phase? #

Great news: your beta data is automatically retained and fully accessible in the GA version. Google never wipes or segregates beta data when a service moves to GA. Firestore’s underlying storage layer didn’t undergo breaking changes during the beta-to-GA transition, so all documents, collections, indexes, and metadata you created with the v1beta1 API will work seamlessly with the stable API.

3. Can all beta data be migrated to the stable version? #

You don’t need to do any manual migration at all. The GA version of Firestore is the same underlying service—just with a polished, stable API surface. Any data written via the beta API is already part of your Firestore project’s storage, and the stable API can read, write, and modify that data without issues.

The only edge case to note: if you relied on highly experimental beta-only features that were deprecated before GA, those might not carry over. But Firestore’s GA release retained nearly all beta functionality (with bug fixes and refinements), so this is rarely an issue for most users.
