    Description

      The IOR codebase needs to be revamped as it has a significant performance problem when dealing with large numbers of namespaces.

      Every time a Gateway resource is modified the IOR codebase queries the k8s api server for routes in every configured namespace, consuming a significant amount of time in larger systems (200/500+ namespaces)

      https://github.com/maistra/istio/blob/dff17a7a330526ed3ed374b31dc45b7d2ab35636/pilot/pkg/config/kube/ior/route.go#L103-L111

      It also has a search based on O(nroutes + ngateways)

      We also need to check if this applies to the 1.1 codebase.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.

          Bug - A problem that impairs or prevents the functions of the product. MAISTRA-2245 IOR queries

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          Task - Represents a small unit of work that is not end-user facing. OSSM-1900 IOR findService queries the API server for each namespace

          • Normal - To be worked after urgent and high priorities are resolved. This term is chosen when the severity of an issue is relatively close to the level of effort to fix it. The existence of an easily implemented workaround can also lead to this priority level instead of a higher priority.
