LGTM.

Can you give an example in the PR description on what the state store url and configuration looks like in order to use obs?

[hzxa21]

cc @neverchanje do we need to mark this as a user facing change and release it in the doc as an supported object store backend?

[neverchanje]

Yes. It's a user-facing feature. The doc team should be aware regardless of whether it's appropriate to document it.

[wcy-fdu]

Yes. It's a user-facing feature. The doc team should be aware regardless of whether it's appropriate to document it.

Yes, this pr is only the kernel side. I will open a pr about docker compose via obs, and need support from doc team and RisingWave operator as well.

Will delivered to customer when all components and documentation are ready.
