Description of problem: The logging function which produces the large range log messages unmarshals the content of the response when it need not do so. This bloats those requests by 10-50% based on some upstream testing. Fixing this could reduce memory consumption substantially on expensive requests and it's fixed upstream in 3.4.16. Version-Release number of selected component (if applicable): OCP 4.6-4.8, etcd-3.4.15 and earlier See upstream issue and PR for more analysis https://github.com/etcd-io/etcd/issues/12835 https://github.com/etcd-io/etcd/pull/12871 Since we should likely just update to the latest, 3.4.18 and that version contains fixes present in 3.5.2 but not 3.5.0 currently utilized by OCP 4.9 I will mark this as being dependent on the existing bugs which track updating 4.9 to 3.5.3. This ensures that we don't update 4.6-4.8 and then regress by upgrading into 4.9 which lacks the same fixes. The logging memory consumption issue is already fixed in etcd 3.5.
Etcd 3.5.3 has been bumped into 4.9 release branch Does this suffice for this bug @sdodson
Unless there's specific reason not to I'd like to see 4.6 through 4.8 bumped to the latest 3.4.z, at least 3.4.16 with the cited fix. If it's too much work to get all those versions then 4.8 will suffice given we see most 4.6 and 4.7 clusters quickly upgrading to 4.8.
Ok, I will start with 4.8 and update here
