Cache gateway and targets lookup when collecting endpoints

Open suzaku opened this issue 4 years ago • 11 comments

Description

When there are hundreds of thousands of VirtualService created, it takes a long time to collect all the endpoints when the external-dns targets are not set explicitly in the annotations of the VirtualService resources.

In my setup, it takes Endpoints about 300ms to figure out the endpoints for 1 VirtualService on average.

This PR tries to add cache to the process, so that no duplicate gateway and target lookup are made. The cache only exists during the Endpoints call, so we don't have to worry about clearing the cache.
