# Which Problems Are Solved
The current maintained gRPC server in combination with a REST (grpc)
gateway is getting harder and harder to maintain. Additionally, there
have been and still are issues with supporting / displaying `oneOf`s
correctly.
We therefore decided to exchange the server implementation to
connectRPC, which apart from supporting connect as protocol, also also
"standard" gRCP clients as well as HTTP/1.1 / rest like clients, e.g.
curl directly call the server without any additional gateway.
# How the Problems Are Solved
- All v2 services are moved to connectRPC implementation. (v1 services
are still served as pure grpc servers)
- All gRPC server interceptors were migrated / copied to a corresponding
connectRPC interceptor.
- API.ListGrpcServices and API. ListGrpcMethods were changed to include
the connect services and endpoints.
- gRPC server reflection was changed to a `StaticReflector` using the
`ListGrpcServices` list.
- The `grpc.Server` interfaces was split into different combinations to
be able to handle the different cases (grpc server and prefixed gateway,
connect server with grpc gateway, connect server only, ...)
- Docs of services serving connectRPC only with no additional gateway
(instance, webkey, project, app, org v2 beta) are changed to expose that
- since the plugin is not yet available on buf, we download it using
`postinstall` hook of the docs
# Additional Changes
- WebKey service is added as v2 service (in addition to the current
v2beta)
# Additional Context
closes#9483

# Which Problems Are Solved
These changes introduce resource-based API endpoints for managing
instances and custom domains.
There are 4 types of changes:
- Endpoint implementation: consisting of the protobuf interface and the
implementation of the endpoint. E.g:
606439a17227b629c1d018842dc3f1c569e4627a
- (Integration) Tests: testing the implemented endpoint. E.g:
cdfe1f0372b30cb74e34f0f23c6ada776e4477e9
- Fixes: Bugs found during development that are being fixed. E.g:
acbbeedd3259b785948c1d702eb98f5810b3e60a
- Miscellaneous: code needed to put everything together or that doesn't
fit any of the above categories. E.g:
529df92abce1ffd69c0b3214bd835be404fd0de0 or
6802cb5468fbe24664ae6639fd3a40679222a2fd

# Additional Changes
When looking for instances (through the `ListInstances` endpoint)
matching a given query, if you ask for the results to be order by a
specific column, the query will fail due to a syntax error. This is
fixed in acbbeedd3259b785948c1d702eb98f5810b3e60a . Further explanation
can be found in the commit message
# Additional Context
- Relates to #9452
- CreateInstance has been excluded:
https://github.com/zitadel/zitadel/issues/9930
- Permission checks / instance retrieval (middleware) needs to be
changed to allow context based permission checks
(https://github.com/zitadel/zitadel/issues/9929), required for
ListInstances
