A few comments.

There are other reasons that you state here https://github.com/dapr/docs/pull/3996/files including

• CockroachDB, YugabyteDB - Should users use this as the preferred component for these over https://docs.dapr.io/reference/components-reference/supported-state-stores/setup-cockroachdb/. If so, would be worth adding something into these component specs to say this

• Is this the preferred version to use over the V1 component? If so, suggest saying this.

CockroachDB will work but not sure if it should have its own component?

As for YugabyteDB, our tests show that it requires a bit of work at this stage. Specifically we need to make users enable the crypto extension for using the UUID generator function

@ItalyPaleAle. A suggestion and comment

• "This is the v2 of the PostgreSQL state store component, which contains some improvements to performance and reliability. It is recommended to use the V2 component over the V1."

• Regarding "CockroachDB will work but not sure if it should have its own component?" - Should users ever use this component for CockroachDB then, or stay with the specific component https://docs.dapr.io/reference/components-reference/supported-state-stores/setup-cockroachdb/ ? Not sure what you mean by "CockroachDB will work but not sure if it should have its own component?" since it already has its own component.

[ItalyPaleAle]

CockroachDB currently has its own documentation, not sure if we should have a v2 of that too
