Specification

https://wicg.github.io/storage-buckets

Summary

Storage Buckets gives sites the ability to organize on-device data into 
separate "buckets", allowing user agents to evict the grouped data 
independently of that which is in other buckets, and enabling sites to 
ergonomically manage semantically related data. Each storage bucket can 
contain data associated with established storage APIs such as IndexedDB and 
CacheStorage.

Can you expand on the OT results? Are the "slow to adoption" comments 
relevant only to the OT itself or to the feature at large?

Risks

Interoperability and Compatibility

If no other browsers end up implementing this API, websites will only be 
able to use the default bucket that is supported today.


Gecko: Positive (https://mozilla.github.io/standards-positions/#storage-
buckets)

WebKit: No signal (https://github.com/WebKit/standards-positions/issues/181)

Web developers: Positive

Other signals:

WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that 
it has potentially high risk for Android WebView-based applications?

Doesn't change existing APIs.


Debuggability

Devtools


Will this feature be supported on all six Blink platforms (Windows, Mac, 
Linux, Chrome OS, Android, and Android WebView)?

No

Is this feature fully tested by web-platform-tests 
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>
?

No

Measurement

Availability expectation

Feature is expected to be available on Firefox, but timeline unknown. 
Implementation in Safari would likely first require widespread use.

Adoption expectation

Expected to be applied **in new projects** soon after launch. Full 
utilization of the API would require data migration, which is not easy and 
may slow adoption in existing projects. Abstractions may be among the first 
adopters as the API is, itself, an abstraction layer that simplifies 
functionality such as namespacing and managing chunks of data.

Adoption plan

We intend to use the Buckets API to expose additional storage-related 
functionality to the web, for example, session-scoped data, performance 
controls, etc. This new functionality will help drive adoption.

Non-OSS dependencies

Does the feature depend on any code or APIs outside the Chromium open 
source repository and its open-source dependencies to function?

No

Anticipated spec changes

Open questions about a feature may be a source of future web compat or 
interop issues. Please list open issues (e.g. links to known github issues 
in the project for the feature specification) whose resolution may 
introduce web compat/interop risk (e.g., changing to naming or structure of 
the API in a non-backward-compatible way).


Open issues/questions are add-only enhancements.
