but in case we have multiple tasks, the dispatch address is culster address? this is what I am confused about.

The dispatch address is

discoveryservicename.discoveryservicenamespace:50053

sorry, the cloudmap nampspace address?

The namespace is a route53 zone. E.g. if you have a private zone named

company.internal

you could make the namespace

authorization.company.internal

and then call the discovery service

spicedb

and then the dispatch address would be

spicedb.authorization.company.internal:50053

this makes sense thank you boss
