[ upstream commit 3e12e02 ] [ Backporter's notes: no error handling in v1.14, different m.Iter part, no health module. closeChan instead of context. ] Before, depending on cluster-size we were triggering node update for each node at fixed intervals depending on cluster-size. This resulted in high cpu usage spike in agent. While the intent is to fix state that got stale and shouldn't be the primary source of updates, it makes sense to spread these updates over time to average out cpu usage. Also, reenable backgroundSync test. Signed-off-by: Marcel Zieba <marcel.zieba@isovalent.com>
[ upstream commit 2019ebe ] [ Backporter's notes: minor conflicts due to lack of context and closeChan instead. ] During bootrstrap, we don't know number of nodes and new implementation essentially was hot looping till fetched nodes. Also, in case of cluster with single node, rate-limiter was not rate-limiting. Fixes #32577 Signed-off-by: Marcel Zieba <marcel.zieba@isovalent.com>
