Please improve gateway - api manager sync performance

Users of our API Connect platform complain about long synchronisation times after a new product/api or a new version of a product/api is published. When the product/api was received and published by API Manager it can take a very long time (sometimes up to 28min), until this new API version can be successfully invoked on the gateway or new subscriptions can be created in the portal and become effective on the gateway.

As in our company API provider teams publish products via self service using a CI/CD pipeline, each team can decide when to publish a new product/api version without synchronizing with other teams or our API Connect platform team. This can lead to situations, where a larger number of products are published within a short period of time. We have seen 300 product publications/updates within 1h where syncs with the gateway taking up to 28 minutes until a published/updated API can be invoked on the gateway.

As our development teams include automatic API testing jobs in their pipelines, the pipeline is blocked, until the api is available on the gateways for test invocations. During high peak loads these pipelines usually fail with a timeout.

Please note, this delay in synchronization also affects portal users. When they create a new subscription it takes very long as well until the can invoke the newly subscribed api e.g. via dev portal try it.

We also created https://integration-development.ideas.ibm.com/ideas/APICONN-I-660 which would allow us to at least query for the api, if it is available, but this will not help to speed up synchronisation

As our APIC users are increasingly complaining about long sync times, please improve synchronization performance between API manager and gateways under high load for product updates. A delay of 2min should be acceptable.
