Comment 1 Hemant Kumar 2017-12-07 21:24:08 UTC

The AttachVolume call count will go down significantly by https://github.com/openshift/origin/pull/17544 But that alone will not bring DescribeVolumes count down. 

Need to think of a strategy for that one, because we need volume information before attach can happen.

Comment 4 Michal Fojtik 2018-01-29 14:24:19 UTC

There seems to be issue upstream about DescribeInstances: https://github.com/kubernetes/kubernetes/issues/31061

But it does not have much activity.

Comment 5 Michal Fojtik 2018-01-29 14:38:31 UTC

There seems to be also a cache for DescribeInstances introduced in:

https://github.com/mfojtik/kubernetes/commit/3d2b71b78fa2995ad20eb8046e34e54c6c2ba88d#diff-17c7fec3373045194f98241891fef960

I will double check if this is doing what we want.

Comment 9 Michal Fojtik 2018-05-07 09:48:26 UTC

I will close this BZ and we can reopen or create new one if this occurs again. I think the kube code got better in caching/limiting the AWS queries.

Also we likely be unable to track and backport all the fixes in AWS query limiting from 3.9 down to 3.7.
