# Which Problems Are Solved
As part of our efforts to simplify the structure and versions of our
APIs, were moving all existing v2beta endpoints to v2 and deprecate
them. They will be removed in Zitadel V5.
# How the Problems Are Solved
- This PR moves instance v2beta service and its endpoints to a
corresponding v2 version. The v2beta service and endpoints are
deprecated.
- The docs are moved to the new GA service and its endpoints. The v2beta
is not displayed anymore.
- The comments and have been improved and, where not already done, moved
from swagger annotations to proto.
- All required fields have been marked with (google.api.field_behavior)
= REQUIRED and validation rules have been added where missing
- `Domain` has been renamed to `CustomDomain` to align with naming
conventions
- `..Query` has been renamed to `..Filter` to align with other services
- The `instance_id` parameter can now passed on all endpoints and is
properly used, but requires `system` permissions. It can be omitted to
use the own instance (identified by context as any other service).
- The following endpoints are affected:
- GetInstance
- UpdateInstance
- ListCustomDomains
- AddTrustedDomain
- RemoveTrustedDomain
- ListTrustedDomains
- InstanceService has been added the InstanceInterceptor's
`explicitInstanceIdServices` to allow passing the id
- If the instance is not found by id, the error is not directly returned
to prevent enumeration.
- Permissions are checked in the API instead of the interceptor for
these calls.
- Setting the same instance name in the update no longer returns an
error, but the previous change date.
# Additional Changes
none
# Additional Context
- part of https://github.com/zitadel/zitadel/issues/10772
- requires backport to v4.x
# Which Problems Are Solved
Comparing the v3 and v4 deployments we noticed an increase in memory
usage. A first analysis revealed that it might be related to the
(multiple) initialization of the `i18n.Translator`, partially related
# How the Problems Are Solved
Initialize the tranlator once (apart from the translator interceptor,
which uses context / request specific information) and pass it to all
necessary middleware.
# Additional Changes
Removed unnecessary error return parameter from the translator
initialization.
# Additional Context
- noticed internally
- backport to v4.x
# 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
