Proposal: implement the full `wasi:keyvalue` spec

[Mossaka]

As the champion of the wasi:keyvalue, a WASI Phase 2 proposal, I am seeking the Spin support in implementing the full specification of the wasi:keyvalue proposal. This would allow us to gather insightful feedback on the design and help advance the proposal to the next stage.

Spin is an early adopter of wasi:keyvalue by implementing the wasi:keyvalue/store interface. Building on this, I propose that Spin extends its support to include the additional interfaces, specifically atomic and batch operations.

• The atomic interface offers atomic operations such as increment and cas, which would make Spin applications that require atomic operations to avoid race conditions possible.
• The batch interface enables applications to operate on multiple keys at once, improving efficiency.

answered your question over wasi:keyvalue repo

I believe this is what @devigned has kindly put his hand up for!

That is correct.

chatted with @devigned who is working on implementation this week. just an FYI

[vdice]

Are we good to close this now that https://github.com/fermyon/spin/pull/2895 is in?

[devigned]

I believe so for 0.2.0-draft2.

[itowlson]

Yeah we can open new issues when the draft changes.

Thank you again for your work on this @devigned.
