Hello @textarea fyi: @dmytro-ch

Could you please provide more details about the use cases and business value of this issue or what dev experience it will improve and how?

[textarea]

Hello @sdzhepa,

I'm sorry but I will not provide more details about the use cases and business value, or about improved dev experience this issue can bring.

When I build a database schema I use all the tools the RDBMS makes available according to my needs.

Magento 2.3 declarative schema misses some foreign key constraints that are supported by standards RDBMS.

Best regards

Any updates on this issue?

That's funny how a one-line fix ticket is not being solved for 4 years. Just add the <xs:enumeration value="RESTRICT" /> line to the Setup/Declaration/Schema/etc/constraints/foreign.xsd file and that's it.
