When building RDS, cache get is always conducted not respecting the PILOT_ENABLE_RDS_CACHE flag. This CL fixes that. Cache add already respects the flag: https://github.com/airbnb/istio/blob/1.14.3-airbnb1/pilot/pkg/networking/core/v1alpha3/httproute.go#L212 Change-Id: Ic0634647239a6def8ced4ce611f5a986f130c95a Reviewed-on: https://gerrit.musta.ch/c/public/istio/+/3611 Reviewed-by: Douglas Jordan <douglas.jordan@airbnb.com> Reviewed-by: Jungho Ahn <jungho.ahn@airbnb.com> Reviewed-by: Weibo He <weibo.he@airbnb.com>

yes, disabling it helps with propagation delay. I posted my testing here: #40744 |
